They were just small wrappers arround cli.Args(), and the abstraction
made one wonder if they were doing some "magic" things, but they weren't,
so just inlining the `cli.Args()` makes it more transparent what's executed.

- Remove `WaitRestart()` as it was no longer used
- Un-export `WaitForInspectResult()` as it was only used internally, and we want
to reduce uses of these utilities.
- Inline `appendDocker()` into `Docker()` as it was the only place it was used,
and the name was incorrect anyway (should've been named `prependXX`).
- Simplify `Args()`, as it was first splitting the slice (into `command` and `args`),
only to join them again into a single slice (in `icmd.Command()`).

iptables -C flag was introduced in v1.4.11, which was released ten
years ago. Thus, there're no more Linux distributions supported by
Docker using this version. As such, this commit removes the old way of
checking if an iptables rule exists (by using substring matching).

The former was doing some checks and logging warnings, whereas
the latter was doing the same checks but to set some internal variables.
As both are called only once and from the same place, there're now
merged together.

These were only used in a single location, and in a rather bad way;
replace them with strings.Cut() which should be all we need for this.

- config collided with import
- cap collided with a built-in
- c collided with the "controller" receiver

This code was forked from libcontainer (now runc) in
fb6dd9766e
From the description of this code:
> THIS CODE DOES NOT COMMUNICATE WITH KERNEL VIA RTNETLINK INTERFACE
> IT IS HERE FOR BACKWARDS COMPATIBILITY WITH OLDER LINUX KERNELS
> WHICH SHIP WITH OLDER NOT ENTIRELY FUNCTIONAL VERSION OF NETLINK
That comment was added as part of a refactor in;
4fe2c7a4db
Digging deeper into the code, it describes:
> This is more backward-compatible than netlink.NetworkSetMaster and
> works on RHEL 6.
That comment (and code) moved around a few times;
- moved into the libcontainer pkg: 6158ccad97
- moved within the networkdriver pkg: 4cdcea2047
- moved into the networkdriver pkg: 90494600d3
Ultimately leading to 7a94cdf8ed, which implemented
this:
> create the bridge device with ioctl
>
> On RHEL 6, creation of a bridge device with netlink fails. Use the more
> backward-compatible ioctl instead. This fixes networking on RHEL 6.
So from that information, it looks indeed to support RHEL 6, and Ubuntu 12.04
which are both EOL, and we haven't supported for a long time, so probably time
to remove this.

Fixes a (theoretical?) panic if ID would be shorter than 12
characters. Also trim the ID _after_ cutting off the suffix.

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
