TST: Fix warnings from Pillow for unavailable features 
If Pillow is old enough to not support a feature _at all_, then it will
warn about it. If you're running the whole test suite, then something
else seems to cause pytest to treat it as benign. But if you run only
`test_agg.py`, then our `-Werror` setting will cause it to fail test
collection.
