Fix mm and mmm in Android.bp directories

mm and mmm were not parsing out/soong/Android.mk, so they were ignoring
all modules defined in an Android.bp file.  Always include
out/soong/Android.mk when ONE_SHOT_MAKEFILE is set, and convert the mm
and mmm functions to build MODULES-IN-$DIR instead of all_modules so
that only the subset of modules defined in out/soong/Android.mk for the
requested directory are built.
