[LTP] [PATCH] statx04: Re-add BTRFS version check

[Richard Palethorpe]

Removing this was a step too far. This causes regressions on products
where there is now no chance of a backport. This is different from the
other version checks which are for much newer kernels. Also there
could be differences in the difficulty of a backport.

Note that I am still very much against new version checks if there is
a high chance of backports. We should leave long established checks
alone however.
