filter: Introduce filter to filter out offset for xfs_io

Browse Source 
Some test cases (AFAIK, btrfs RAID recovery test cases) read out
certain location to verify its data.

Such read is mostly OK, but the golden output contains the on-disk
offset, which can differ due to underlying chunk change.  (This time
is mkfs chunk layout change for btrfs)

So introduce macro _filter_xfs_io_offset to filter out the offset part
wrote 65536/65536 bytes at offset 136708096
                       ^^^^^^^^^^^^^^^^^^^^
And offset from "pread -v"
08260000:  aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa  ................
^^^^^^^^^

Only btrfs/14[0-3] are affected.
