Modify _require_odirect() to skip O_DIRECT tests if the ext4 mount option data=journal has been applied. Because ext4 disables its O_DIRECT support when in data journaling mode, no significant value is obtained by running these tests and they consume a significant amount of run time. Additionally, this change eliminates the need to triage false negative O_DIRECT test results caused by test problems, as has occurred from time to time.
