Adjust debugger test suites for macos

Namely, after trying to get `test_multi_daemon_subactors` to work for
the `ctlc=True` case (for way too long), give up on that (see
todo/comments) and skip it; the normal case works just fine. Also tweak
the `test_ctxep_pauses_n_maybe_ipc_breaks` pattern matching for
non-`'UDS'` per the previous script commit; we can't use UDS alongside
`pytest`'s tmp dir generation, mega lulz.
