units: don't stop blockdev@.target unit at shutdown

We want that cryptsetup/veritysetup devices can stick around until the
very end, as well as the users of them which might depend on
blockdev@.target for the devices. Hence leave the targets around till
the very end.

Note that their runtime is managed via StopWhenUnneeded= anyway, hence
unless their are volumes that actually survive still the very end they
target units will still be stopped.
