examples/gps: show units in output

Browse source 
The GPS example prints parsed measurements without explicit units. The RMC
floating-point speed path also used minmea_tocoord(), even though speed is
not a coordinate.

Add units to the output labels, print speed with minmea_tofloat(), and print
GGA altitude as a scaled value with the sentence-provided unit.
