[PATCH] fstests: btrfs/157 btrfs/158: Prevent stripe offset to pollute golden output

[Qu Wenruo <wqu@suse.com>]

Test btrfs/157 and btrfs/158 are verifying the repair functionality of
supported RAID profile, thus it needs to corrupt the fs data manually using
physical offset of data.

However that physical offset of data is dependent on chunk layout, which
is further dependent on mkfs, so such physical offset is never reliable.

And btrfs-progs commit c501c9e3b816 ("btrfs-progs: mkfs: match devid
order to the stripe index") changed the mkfs stripe layout, the golden
output no longer matches the output.

This patch will remove the physical offset from golden output,
especially since we already have those offsets output in seqres.full.
