Move the MCONFIG files into a mk/ directory and give them more
descriptive names.

This is purely a cosmetic change to make the 'include' directives a
bit more coherent by making it obvious exactly which MCONFIG file
we're including. For example, in com32/lua/src/Makefile we exchange
the line,

	include ../../MCONFIG

for the much more comprehensible,

	include $(MAKEDIR)/com32.mk

The old name was intended as a test to prevent collision.  New name
seems more logical and appropriate.  By reusing the mem= parameter and
adjusting all of the memory calls that MEMDISK replaces through the use
of insertrange(), there's nothing better that we can do.
