The same attribute was generated for each path that was created, but always
the same, so instead of generating it in each iteration, generate it once,
and pass it to our mkdirall() implementation.

The regex only matched volume paths without a trailing path-separator. In cases
where a path would be passed with a trailing path-separator, it would depend on
further code in mkdirall to strip the trailing slash, then to perform the regex
again in the next iteration.
While regexes aren't ideal, we're already executing this one, so we may as well
use it to match those situations as well (instead of executing it twice), to
allow us to return early.

Ideally, we would construct this lazily, but adding a function and a
sync.Once felt like a bit "too much".
Also updated the GoDoc for some functions to better describe what they do.

Migrating these functions to allow them being shared between moby, docker/cli,
and containerd, and to allow using them without importing all of sys / system,
which (in containerd) also depends on hcsshim and more.

filepath.IsAbs() will short-circuit on Linux/Unix, so having a single
implementation should not affect those platforms.

The io/ioutil package has been deprecated in Go 1.16. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

This struct now has a properly typed member, so use the properly typed
functions with it.
Also update the vendor directory and hope nothing explodes.

Some permissions corrections here. Also needs re-vendor of go-winio.
- Create the layer folder directory as standard, not with SDDL. It will inherit permissions from the data-root correctly.
- Apply the VM Group SID access to layer.vhd
Permissions after this changes
Data root:
```
PS C:\> icacls test
test BUILTIN\Administrators:(OI)(CI)(F)
NT AUTHORITY\SYSTEM:(OI)(CI)(F)
```
lcow subdirectory under dataroot
```
PS C:\> icacls test\lcow
test\lcow BUILTIN\Administrators:(I)(OI)(CI)(F)
NT AUTHORITY\SYSTEM:(I)(OI)(CI)(F)
```
layer.vhd in a layer folder for LCOW
```
.\test\lcow\c33923d21c9621fea2f990a8778f469ecdbdc57fd9ca682565d1fa86fadd5d95\layer.vhd NT VIRTUAL MACHINE\Virtual Machines:(R)

Files that are suffixed with `_linux.go` or `_windows.go` are
already only built on Linux / Windows, so these build-tags
were redundant.
