ext2sim: Makefile target for: finds sim2simp

Not a serious attempt to make these work but they appear to compile
so this helps CI to cover as much code as possible.

ext2sim_main standalone does not link (probably due to unclean cross
module dependencies that now exist due to libutil.a being a heap where
anything with no modular home ends up)
