[VOL-5321] - Add repo:onf-make as a git submodule.

Makefile
lf/transition.mk
----------------
  o Add bridge logic to conditionally load legacy makefiles or repo:onf-make.
  o transition.mk allows logic to gradually be replaced.
  o makefiles/ directory can eventually be removed after all
    dependencies on local makefile logic have been removed.

makefiles/
----------
  o Replace make var(s) ONF_MAKEDIR= and ONF_MAKE= with var legacy-mk=.

makefiles/commands/include.mk
makefiles/commands/kail/godownloader.sh
---------------------------------------
  o Replace loading legacy kail logic with library makefiles.
  o Git submodule scripts contain linting cleanup for scripts.
