test: simplify rules-test.sh wrapper

Drop globbing of rules/*.rules in the rules-test.sh wrapper and move that logic
into the actual test rule-syntax-check.py. This can still be called with
individual rules files, but when being called without arguments it will now
process all top_builddir/rules/*.rules.

Preparation for dropping the shell wrappers altogether.
