    tests: Fix gengiotypefuncs.py helper script
    
    It seems this script has potentially never worked properly under Python
    3. It’s supposed to list all the `_get_type()` functions it can find in
    the GIO headers, but since the regex string passed to `re.search()` was
    not a Python regex, nothing was matching.
    
    Fix that, and do another few small cleanups to the script.
    
    This makes the `defaultvalue` test not skip all the types.
