machined: generate a nicer error when the user tries "machinectl clone" on non-btrfs file systems (#3117)
Fixes: #2060 (Of course, in the long run, we should probably add a copy-based fall-back. But given how slow that is, this probably requires some asynchronous forking logic like the CopyFrom() and CopyTo() method calls already implement.)
