e2fsck, libext2fs: support for bigalloc file systems with a blocksize of 1024

Filesystems with a blocksize of 1024 have the superblock starting at
block #1.  However, the first data block in the superblock is 0 to
simplify the cluster calculations.  So we must compensate for this in
a number of places, mostly in the ext2fs library, but also in e2fsck.
