sysmobts_mgr: Prepare code for gpsd < 2.96 support

API prior to that version allocates the pointer internally. Let's change
current code to always use a pointer and in current supported code (gpsd
>= 2.96) point it to a user-allocated struct.

Follow-up patch will introduce necessary ifdefs to support older gpsd.
