build system: Makefile.in: always include cfgdefs.mk & usrdefs.mk.

The purpose of this commit is twofold; from the user's perspective, this
provides a consistent experience whenever building a sofort-based project;
and from the developer's perspective, this provides an easy way to test
cfgdefs.mk even before the writing and/or integration of cfgdefs.sh.
