systemctl: restore the no-sync option for legacy halt (#3249)
The sync() call on shutdown had been removed with commit 57371e5829a61e5ee6c9f98404dfc729d6c62608
together with the no-sync option for the shutdown commands.
The sync call was restored in commit 4a3ad39957399c4a30fc472a804e72907ecaa4f9 but the no-sync option
wasn't re-added.
I think we should restore this option at least for the legacy halt command.
