Brad Fitzpatrick b56058d7e3 tool/gocross: fix regression detecting when gocross needs rebuild
Fix regression from #8108 (Mar 2023). Since that change, gocross has
always been rebuilt on each run of ./tool/go (gocross-wrapper.sh),
adding ~100ms.  (Well, not totally rebuilt; cmd/go's caching still
ends up working fine.)

The problem was $gocross_path was just "gocross", which isn't in my
path (and "." isn't in my $PATH, as it shouldn't be), so this line was
always evaluating to the empty string:

    gotver="$($gocross_path gocross-version 2>/dev/null || echo '')"

The ./gocross is fine because of the earlier `cd "$repo_root"`
