tests: new test to check quota after a bad inode deallocation

This new test validates e2fsck by verifying that quota is updated after a bad
inode is deallocated.  It mimics fstest ext4/019 by including a filesystem image
where a symbolic link was created to an existing file, using a long symlink
name.  This symbolic link was then wiped with:

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