Makefile: match shell scripts in FIND_SOURCE_FILES
We feed FIND_SOURCE_FILES to ctags to help developers navigate to particular functions, but we only feed C source code. The same feature can be helpful when working with shell scripts (especially the test suite). Modern versions of ctags know how to parse shell scripts; we just need to feed the filenames to it. This patch specifically avoids including the individual test scripts themselves. Those are unlikely to be of interest, and there are a lot of them to process. It does pick up test-lib.sh and test-lib-functions.sh. Note that our negative pathspec already excludes the individual scripts for the ls-files case, but we need to loosen the `find` rule to match it.
