Input: Allow compile test of Goodix and Colibri VF50 if !GPIOLIB

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.

If COMPILE_TEST is enabled, relax the dependency on GPIOLIB for the
recently introduced or relaxed symbols TOUCHSCREEN_GOODIX and
TOUCHSCREEN_COLIBRI_VF50.
