dbus-daemon test: don't assert we pass uid/pid on unknown Unix platforms

We know that Linux, FreeBSD and OpenBSD are "first class citizens"
for credentials-passing, with NetBSD not far behind: people have
turned up on the bug tracking system and told us that tests passed.
On other Unixes, we can't really assert that it works, until someone
who runs them tells us that it worked for them.

Additions to these lists are welcome.
