[PATCH v2] ext4/01{2,9}: fix invalid filesystem option 'journal'

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

Creating an ext4 filesystem using '-O journal' will fail with:

    Invalid filesystem option set: journal

Fix it by replacing it by '-O has_journal', which ensures the filesystem
(ext3 or ext4) is created with a journal.  While there, also redirect stderr
and stdout to the full log.

changes since v1 (after tytso's review):
- instead of dropping '-O journal', replace it by '-O has_journal'
- redirect std{out,err} to log
- use _scratch_mkfs instead of _scratch_mkfs_ext4
