This changes many tests to use require when checking 'istarget'. A few of these conversions were already done in earlier patches. No change was needed to 'require' to make this work, due to the way it is written. I think the result looks pretty clear, and it has the bonus of helping to ensure that the reason that a test is skipped is always logged.
