Prettify expired rules printing

Prettify expired rules printing

"pfctl -s rules"    omits expired rules but print newlines for them.
"pfctl -s rules -v" omits expired rules but print their stats.

Add the existing skip check to those two missing print logic places such
that expired rules won't cause any output at all, as expected, unless
debug ("-g") or more verbose ("-vv") mode are given, as documented.
