[PATCH 3/4] tests: new test to check quota after directory optimization

["Luis Henriques (SUSE)" <luis.henriques@linux.dev>]

This new test validates e2fsck by verifying that quota data is updated after a
directory optimization is performed.  It mimics fstest ext4/014 by including a
filesystem image where a file is created inside a new directory on the
filesystem root and then root block 0 is wiped:

  # debugfs -w -R 'zap -f / 0' f_testnew/image
