Skip tests know to fail under Python 2.6

[Matt Molyneaux]

As stated in #909, there are some tests that fail under Python 2.6. Until pytest is fixed we should skip these tests when we detect we're running Python 2.6.

Just to be sure that these tests are failing because of #909, here's the relevant output of .runtests.sh:

As of v0.8.0, MediaGoblin has dropped support for Python 2.6. Is there any reason not to close this ticket as wontfix?
