Illumos/OpenIndiana/SunOS/Solaris has an rm/rmdir that tries to protect the user by not allowing them to delete $PWD. Normally, this would be a good thing as deleting $PWD is a stupid thing to do. Except in this case, we absolutely need to do that. So instead we weasel around it by invoking an sh to cd out of the directory to then invoke an `rmdir` to delete it. That should throw off any attempts at protection (we could also have tried $PWD/. or similar, but that's possibly still protected against). This is the last failing test on Illumos/OpenIndiana/SunOS/Solaris/afunnyquip, so: Fixes #5472.
