[1/2,bigalloc] e2fsprogs: change "blocks" to "clusters" in dumpe2fs

From: Robin Dong <sanbai@taobao.com>

When using dumpe2fs to display group detail of a bigalloc-fs, it displays like:

Group 413: (Blocks 54132737-54263808)
Block bitmap at 54132737 (+0), Inode bitmap at 54132738 (+1)
Inode table at 54132739-54133761 (+2)
8127 free blocks, 8184 free inodes, 0 directories
Free blocks: 54133776-54263792
Free inodes: 3379993-3388176

The "8127 free blocks" should be "8127 free clusters".

This patch is based on "next" branch of e2fsprogs.

Perhaps it is good to show both the free clusters and the equivalent free blocks, or maybe even free kB, since having units of e.g. 64kB clusters is hard to understand.
