skimage is marked for autoremoval from testing

[Thomas Caswell]

For reference mpl also had the same request
https://github.com/matplotlib/matplotlib/issues/4927 and went with a
nuclear version of option 1 (
https://github.com/matplotlib/matplotlib/pull/4928) but we had already
removed the image from all of our examples/tests.
