devmapper/Remove(): use Rmdir, ignore errors
devmapper/Remove(): use Rmdir, ignore errors

1. Replace EnsureRemoveAll() with Rmdir(), as here we are removing
   the container's mount point, which is already properly unmounted
   and is therefore an empty directory.

2. Ignore the Rmdir() error (but log it unless it's ENOENT). This
   is a mount point, currently unmounted (i.e. an empty directory),
   and an older kernel can return EBUSY if e.g. the mount was
   leaked to other mount namespaces.
