tests: new test to check quota after directory optimization

This new test validates e2fsck by verifying that quota data is updated after a
directory optimization is performed.  This issue was initially found by fstest
ext4/014, and this test was based on it.  It includes a filesystem image where
the lost+found directory is unlinked after a new link to it is created:

  # debugfs -w -R "ln lost+found foo" f_testnew/image
  # debugfs -w -R "unlink lost+found" f_testnew/image
