Added needed chmod'ing to fix stage1

I'm pretty sure this is the minimal set of files to make things work, but feel free to experiment.

We still need to figure out why I'm the only one this failed for, and write some tests. I suspect it may be that I had to run as root, due to lix not allowing the `--system` argument when run by an ordinary user. I don't think we, uh, have a test framework yet, so I'm leaving that for another CL...
