tools/qa-checks: Add file filtering via include_patterns

Added include_patterns to recursively_apply_check in common.py.
If provided only files matching the patterns will be checked.
Only files which aren't excluded (by exclude_patterns or file_types
settings) will be considered for include_patterns.
