devroot: Fix stat and clean up rootgen.

Stat on directories didn't work.  It was doing the usual devstat() thing
where devstat() makes a fake entry.  But we can actually do better, by
implementing rootstat directly.  Since we're trying to be a filesystem, we
shouldn't be using the synthetic solutions (e.g. devstat), which get the
timestamps and usernames wrong.

Likewise, I cleaned up rootgen() a little.  We had been taking a dirtab
pointer, but not actually using it (except in one odd case), which was
confusing.
