Kir Kolyshkin daeab40b45 os.Unmount: do not consult mountinfo, drop flags 
1. Currently, Unmount() call takes a burden to parse the whole nine yards
of /proc/self/mountinfo to figure out whether the given mount point is
mounted or not (and returns an error in case parsing fails somehow).

Instead, let's just call umount() and ignore EINVAL, which results
in the same behavior, but much better performance.

This also introduces a slight change: in case target does not exist,
the appropriate error (ENOENT) is returned -- document that.

2. As Unmount() is always used with MNT_DETACH flag, let's drop the
flags argument. This way, the only reason of EINVAL returned from
umount(2) can only be "target is not mounted".

3. While at it, remove the 'containerdmount' alias from the package.
