status: support commands.status.relative config

When the config is set to true, status output becomes relative to the
working directory. This has bugged me since I started using hg and it
turns it is sillily simple to support it (unless I missed something,
of course).

We could also add a --relative flag, but I would personally always
want that on, and I haven't heard any use for having it sometimes on,
so this patch only lets you enable it via config.
