Re-implement mma/mmma using make goals.
Previously we use command line variable BUILD_MODULES_IN_PATHS which
causes kati to regenerate build.ninja if any variable value changes.
TODO: Remove the old rules of BUILD_MODULES_IN_PATHS in
build/core/main.mk and ninja.mk once users have re-sourced envsetup.sh.
Probably in a few weeks.
Caveat: With this change, if a user sources the new envsetup.sh, mma/mmma
won't work in old branches from the same shell.
