Run tests that do not have any compile targets if source files change

Run tests that do not have any compile targets if source files change

This change makes tryjobs run tests that don't have any compile targets (check_deps, 
check_perm, etc) if there are source file changes. This fixes the problem that changes 
that don't impact linux can break check_deps since linux trybots are the only ones that 
run the check_* tests.
