tests: Makefile change avoiding compiler error for module test

wpa_supplicant was giving below error when "CONFIG_MODULE_TESTS=y" and
"CONFIG_P2P=y" are in .config file:
"wpas_module_tests.c:84: undefined reference to `wps_module_tests'"

This error is coming because "CONFIG_WPS=y" is commented out in .config
file but CONFIG_WPS is getting enabled by CONFIG_P2P in Makefile.
