Use the same build.ninja for normal make targets

Use the same build.ninja for normal make targets

$(PARSE_TIME_MAKE_GOALS) is a list of known goals which affect
parsing of make (e.g., there is $(filter XXX,$(MAKECMDGOALS))).
If the make targets contain one of them, we keep using a
different build.ninja for each combination of make targets.
Otherwise, we use the same build.ninja which has all phony
targets.

Also load vendor/google/build/ninja_config.mk so it can add
Google-specific goals to $(PARSE_TIME_MAKE_GOALS).
