[Buildroot] [PATCH 1/1] gpsd: enable kpps support

[James Knight]

GPSD has the ability to support KPPS. Its enablement is determined
primarily from the existence of `sys/timepps.h`. This file is provided
from the pps-tools package. Adjusting GPSD's Makefile to depend on the
pps-tools package if a developer has included pps-tools as part of a
build.
