Subzero: Add "szbuild_spec2k.py --run" option.

This makes it easier to do bisection debugging. Note that this could be used to simplify "make -f Makefile.standalone check-spec", but I chose not to do that because shellcmd() buffers all of the stdout until completion, which is not a great user experience (at least for this user).
