tgf: Introduce GfParmReadFileBoth

Browse source 
This new function attempts to read a parameter file from GfLocalDir()
first, and from GfDataDir() if not successful.

This function will be useful to extract car and track data from both
directories. Having car and track data available from GfLocalDir() is
required to allow users downloading new cars and tracks without
administrator/root privileges.
