Reland 'Update expectations for skimage.'

Now that expectations have moved to use the builder_name rather than
the gm_subdir (see https://code.google.com/p/skia/source/detail?r=10923),
check in a new set which uses the proper name.

Reverted in https://code.google.com/p/skia/source/detail?r=10970
due to failures on builders without an attached device. Can
resubmit once https://codereview.chromium.org/23495007/ is
submitted.
