[PATCH 3/3] common/rc: support gfs2 in _scratch_mkfs_sized

[Andrew Price <anprice@redhat.com>]

This enables tests which use _scratch_mkfs_sized when $FSTYP == gfs2.
Where tests use a fs size too small to contain a gfs2 fs created with
default options, specify a smaller journal size to make it fit.
