Fix build against gpsd >= 3.20 

The previous version was written against gpsd 3.10. This also makes the
date more precise, previously microseconds were set to 0.

GPSD_API_MAJOR_VERSION is defined in gps.h, together with a changelog:
https://gitlab.com/gpsd/gpsd/-/blob/master/include/gps.h

Use Pau's compat_gps_read() from:
https://gerrit.osmocom.org/c/osmocom-bb/+/11609
