[PATCH] xfstests: 223 - test file alignment on stripe geometry

I'd make this generic and just do the notrun in scratch_mkfs_geom for
non-supported filesystems.

And I'd throw this one into common.rc.

Hmm, doesn't this change break other testcase?  Anyway needs some
rationale in the changelog.

This is a bit misnamed as it's not a generic fibmap tool but rather
a specific tool comparing the bmap to the sunit alignment.
