mke2fs: do not set the BLOCK_UNINIT on groups has GDT

This patch prepares the expansion of GDT blocks beyond a
single group, by make mke2fs to not set BLOCK_UNINIT on
groups with GDT blocks, block/inode bitmaps, or inode table
blocks allocated.

Otherwise, we still rely on kernel side to initialize the
block bitmap if the groups has BLOCK_UNINIT set, and the
kernel doesn't know a group could have GDT blocks allocated,
so it would make an bad block bitmap.

As a result, expect output of several tests needs to be changed,
especially if the test uses dumpe2fs to print the group summary.
