[PATCH v2 8/7] xfs/122: don't break on old xfsprogs

[Darrick J. Wong]

If we're running against a old version of xfsprogs that lacks some of
the structures that the golden output knows about, copy the structure
size definition from the golden output to the program output.  This
way we can check for structure size mutations on old xfsprogs without
generating false error reports for structs that don't exist in the
old release.

v2: Remove the xfsprogs 2.9.8 compatibility cruft.
