Added new filesystem directories.

Fixed munged whitespace (just 2 lines of it).  The mtree files were
originally generated by `mtree -cdinx -kuname,gname,mode'.  This
gives output with no tabs except in the header.  The format should
be preserved by manual updates so that the files don't change a
lot when they are regenerated.
