selinux: Don't fail RestoreAll if file doesn't have a default label

When restoring selinux labels after a VM is stopped, any non-standard
path that doesn't have a default selinux label causes the process
to stop and exit early. This isn't really an error condition IMO.

Of course the selinux API could be erroring for some other reason
but hopefully that's rare enough to not need explicit handling.

Common example here is storing disk images in a non-standard location
like under /mnt.
