TestSocket_UNIXSocket: stop testing empty packets

OpenBSD and Solaris behave differently here.

Linux does deliver the empty packet, which is questionable
as it's undistinguishable from a closed connection.

It seems that OpenBSD and Solaris simply drop it.

We could test the platform before doing the assertion, but
it would likely be fragile, and the entire web recommend
to not ever send an empty packet, so the value of this
assertion is low.
