Hookup mkcsmapper_static and mkesdb_static for all but install.

Hookup mkcsmapper_static and mkesdb_static for all but install.

These are only handled as 'build-tools' in Makefile.inc1.  This causes
'make clean' from the top of the tree to not clean the directories.  It also
effectively has kept them disconnected and risks them bitrotting.  The
buildworld process never cleans them either.

Connect them so they will always be built, cleaned, etc, but never installed.
