[LITMUS^RT] [PATCH 1/2] Add module support in Makefile

[Manohar Vanga]

This is a slightly hacky method of introducing modules support for
liblitmus. Then again, Makefile's tend to be hacky anyway. This
patch enables the development of LITMUS^RT tasks in their own folders
with a kernel-style Makefile.
