cmm: re-run automake and change dependency on libcmm.

This wasn't building for me at all in a fresh build because you can't link
to -lcmm until after doing 'make install', but we were attempting to build
programs that linked with -lcmm.  Leftover stuff in the staging directory
would have make it build if you weren't building from scratch.

Also fix a missing dependency on module_l2tp.c in the Makefile.am, and
re-run automake.  Someone had been manually editing Makefile.in instead of
its source file, Makefile.am.
