gps: Add A-GLONASS Position protocol in gps.conf

OEMs rely on gps.conf to config gps features. We want to have
default config in the conf file however to both serve as
recommendeded setting and as setting template. This added
A-GLONASS protocol is already supported by the current
implementation. Now we are adding the default config to the
conf file."
