GPS time without date was previously used to set system date:
Tue Oct 10 11:48:21 2000 user.info kernel: [ 108.786639] ugps: system time differs from GPS time by more than 5 seconds. Using 2000-10-10T10:48:21 UTC as the new time
Tue Oct 10 11:49:27 2000 user.info kernel: [ 174.794699] ugps: system time differs from GPS time by more than 5 seconds. Using 2020-05-26T10:49:27 UTC as the new time
Fix this by ignoring incomplete dates and wait for complete time
information before adjusting system date/time.

This extra _DEFAULT_SOURCE definition results in a double definition
which is a compile error.
This fixes the following compile error with glibc:
----------------------------------------------------------------------
ugps-2019-06-25-cd7eabcd/nmea.c:19: error: "_DEFAULT_SOURCE" redefined [-Werror]
#define _DEFAULT_SOURCE
<command-line>: note: this is the location of the previous definition
