I fixed the webkit-misc bot (which was the one in a bad state)

The issue here is that we're caching installed libraries, so if someone posts a bad patch, it has the potential to break our cache on one of these bots. There are a few things we could do to fix it (like clearing out our autoinstalled libraries when running webkitpy tests), but I think I'd rather just deal with the occasional bot being in a bad state than the potential network issues we may encounter re-installing all our libraries every time.
