check-code: skip unhandled files

check-code is organized into a list of file patterns for which there
are a list of string patterns in which to look for strings (and then
complain if matches are found).

It doesn't make sense to open files for which there are no matching
file patterns. So, we compile the matching file patterns and then
skip anything that doesn't match them.
