Only generate versions in SBCL git checkouts

Browse source 
Sometimes larger build systems contain copies of SBCL sources, if those
systems are managed with git, we don't want to trample version.lisp-expr
with _their_ version, but keep the version of SBCL.

Attempt to detect this by checking whether
`git rev-parse --show-top-level`/run-sbcl.sh exists, if not assume git
is operating on a checkout of something other than SBCL
