Corrupting ext4 and f2fs relies on xfs_io fiemap. Btrfs corruption
testing will rely on a btrfs specific corruption utility. Add the
ability to require corruption functionality to make this properly
modular. To start, just check for fiemap, as that is needed
universally for _fsv_scratch_corrupt_bytes.
