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.
