systemctl: don't allow --wait with commands that might not start units

Browse Source 
There's no good reason to use `--wait` with ReloadOrRestartUnit, or
TryRestartUnit.

The message was also wrong in another sense.  'systemctl isolate'
starts units, but it did not support `--wait`.  Although it's
unlikely anyone would want to do that in the first place.
