Subject: [PATCH] core/unit: unit_is_filtered() -> unit_passes_filter() and
 invert logic

Follow-up for 6d2984d21bf2a8f71d379ef6bc13a761bb2e2756

The current semantics of "filtered" in unit_is_filtered()
are actually the contrary of ListUnitsFiltered(). Let's
make things consistent, i.e. return true when the unit
shall be included.
