Simplify the test and fix ext4/050 failures when running ext4 without extents enabled (e.g., in ext3 emulation mode). Instead of relying on parsing debugfs output's (which varies depending on whether the journal inode is extent mapped or indirect block mapped), use debugfs's "cat" command to get the contents of the journal.
