libblkid: (bcachefs) fix not detecting large superblocks

Probing does not detect bcachefs filesystems with a superblock larger
than 4KiB. Bcachefs superblocks grow in size and can become much larger
than this.

Increase the superblock maximum size limit to 1MiB.

Validate the superblock isn't larger than the maximum size defined in
the superblocks layout section.
