gbproxy: Add quirk commands to allow upgrade from pre-release 

The pre-release didn't add a newline after the apn and the patching
pattern command. Create a quirk command that combines both. The
pre-release didn't include a differentation between routing and
patching.

The TLLI handling has a different and more generic name now. Make
it handle the old one that is actively used.

Add a file with the broken format and the standard config file
test should pick it up.
