We're looking for a specific prefix, so remove the prefix instead. Also remove
redundant error-wrapping, as `os.Open()` already provides details in the error
returned;
open /no/such/file: no such file or directory
open /etc/os-release: permission denied

This was caught by goimports;
goimports -w $(find . -type f -name '*.go'| grep -v "/vendor/")
CI doesn't run on these platforms, so didn't catch it.

This also fixes the GetOperatingSystem function in
pkg/parsers/operatingsystem which mistakenly truncated utsname.Machine
to the index of \0 in utsname.Sysname.

This function was only used in a single place, and pkg/parsers/operatingsystem
already copied the `verNTWorkstation` const, so we might as well move this function
there as well to "unclutter" pkg/system.
The function had no external users, so not adding an alias / stub.

Microsoft has stopped updating the ProductName registry value in Windows
11; it reads as Windows 10. And Microsoft has made it very difficult to
look up the real product name programmatically so that applications do
not attempt to parse it. (Ever wonder why they skipped Windows 9?) The
only documented and supported mechanisms require WMI or WinRT. The
product name has no bearing on application compatibility so it is not
worth doing any heroics to display the correct name. The build number
and Update Build Revision is sufficient information to identify a
specific build of Windows. Stop displaying the ProductName so as not to
confuse users with incorrect information.
Microsoft has frozen the ReleaseId registry value at 2009 when they
switched to semi-annual releases and alpha-numeric versions. The release
version as displayed by winver.exe and Settings -> System -> About on
Windows 20H2 and newer can be found in the new DisplayVersion registry
value. Replicate the way winver.exe displays the version by
preferentially reporting the DisplayVersion if present and reporting if
it is a Windows Server edition.

Not really bullet-proof, users can still create cgroups with name like
"foo:/init.scope" or "\nfoo" to bypass the detection. However, solving
these cases will require kernel to provide a better interface.

This is needed so that we can add OS version constraints in Swarmkit, which
does require the engine to report its host's OS version (see
https://github.com/docker/swarmkit/issues/2770).
The OS version is parsed from the `os-release` file on Linux, and from the
`ReleaseId` string value of the `SOFTWARE\Microsoft\Windows NT\CurrentVersion`
registry key on Windows.
Added unit tests when possible, as well as Prometheus metrics.

RHEL/CentOS 3.10 kernels report that kernel-memory accounting is supported,
but it actually does not work.
Runc (when compiled for those kernels) will be compiled without kernel-memory
support, so even though the daemon may be reporting that it's supported,
it actually is not.
This cause tests to fail when testing against a daemon that's using a runc
version without kmem support.
For now, skip these tests based on the kernel version reported by the daemon.
This should fix failures such as:
```

Using a value such as `--cpuset-mems=1-9223372036854775807` would cause
`dockerd` to run out of memory allocating a map of the values in the
validation code. Set limits to the normal limit of the number of CPUs,
and improve the error handling.

order to get the unix.Utsname with byte array instead of int8/uint8

This allows to use simple byte slice to string conversions instead of
using charsToString or its open-coded version.
