filter: inode size output of mkfs.xfs can change

With the change to CRCs by default, the mkfs inode size is defaults
to 512 bytes and the minimum block size changes to 1024 bytes. This
causes mismatches with golden output that expects the inode size to
be 256 bytes, and some tests are tailored around the amount of space
inside a 256 byte inode. Fix them with appropriate filtering or mkfs
parameters to allow 256 byte inodes to be used.
