Subject: [PATCH] tests: check updating the orphan file checksums during an
 offline resize

Check to make sure resize2fs correctly update the orphan file's
checksums if the orphan_file's blocks get moved.

This test checks the fix in commit ff4f46b4fdb2 ("resize2fs: rewrite
the checksums in the orphan file if necessary").
