blkid: recognize ext4(dev) without journal

ext4/ext4dev no longer require a journal.

w/o this blkid doesn't recognize after:

# mkfs.ext4 /dev/blah
# tune2fs -O ^has_journal
# blkid /dev/blah

We still must have one ext3-incompat-feature to flag
as ext4(dev) so we shouldn't ever mis-recognize it.
