[PATCH 5/6] tests: add f_first_meta_bg_too_big test

["Theodore Ts'o" <tytso@xxxxxxx>]

The test verifies that e2fsck can properly fix a file system where the
value of s_first_meta_bg in the superblock is larger than the number
of block group descriptors in the file system.  E2fsck will fix this
by clearing the meta_bg feature.
