mkfs.minix: The total number of zones is limited to 65536 only on V1 filesystems

mkfs.minix: Some bug fixes:

- Fix root inode initialization
- In V3 filesystems the maximum number of inodes is not 65536 but 2^32.

mkfs.minix: The s_blocksize field of the MinixV3 superblock must be
initialized with a valid block size, not the total number of blocks
of the device!

mkfs.minix: inode numbers are 32-bit wide in V3 filesystems

mkfs.minix: In Minix V3 filesystems the maximum filename lenght is 60
chars and the dirsize is 64 bytes.

mkfs.minix: Fix super_set_nzones()

Write the total number of zones in Super3.n_zones when
dealing with v3 filesystems.
