subunit/run.py: make iso8601 UTC usage python 2/3 compatible

In `iso8601/iso8601.py`:

    if sys.version_info >= (3, 2, 0):
        UTC = datetime.timezone.utc
        ...
    else:
        class Utc(datetime.tzinfo):
            ...

        UTC = Utc()

The class `Utc` is only available for python < 3.2.0.
Use `UTC` instance instead, which is python 2/3 compatible.
