mkfs.erofs supports creating filesystem images with different
blocksizes. Add filesystem blocksize in super block dump so
its easier to inspect the filesystem.
The filed is added at last, so the output now looks like:
Filesystem magic number: 0xE0F5E1E2
Filesystem blocks: 21
Filesystem inode metadata start block: 0
Filesystem shared xattr metadata start block: 0
Filesystem root nid: 36
Filesystem lz4_max_distance: 65535
Filesystem sb_extslots: 0
Filesystem inode count: 10
Filesystem created: Fri Apr 12 15:43:40 2024
Filesystem features: sb_csum mtime 0padding
Filesystem UUID:
a84a2acc-08d8-4b72-8b8c-b811a815fa07
Filesystem blocksize: 65536
