git-instaweb: Fix Apache environment variable passing
git-instaweb: Fix Apache environment variable passing

We were passing the non-existent GIT_EXEC_DIR through instead of the real
GIT_EXEC_PATH. In addition, these weren't being passed at all for CGI (non
mod_perl) execution so get them included there as well.
