Gypsy plugin: add satellite identifier and satellite system information

Gypsy daemon provides the satellite_id of the available satellites, but
this information was never used before.
We can also try to determine the satellite system based on the satellite
identifier.

Task-number: QTBUG-74995
Pick-to: 6.2
Change-Id: I7eba052034ddb7b64d91a81381d136bf9f2ddeca
