build: fix syntax-check rules broken by test-added .sh/pl suffixes

* cfg.mk: We exempt a few test files that would otherwise trigger
false-positive matches in syntax-check rules.  The recent change
that added a .sh or .pl suffix to each test script made it so
some of the exclusion regexps would no longer match.
Include the required \.sh suffix in each such regexp, too.
