TST: prefer pytest.skip() over SkipTest

* replace most usage of SkipTest() with
pytest.skip()

* where possible, we avoid use of the standard
library SkipTest because unittest skipping
is routed through the pytest nose compatibility
layer in that scenario, which can prevent an easy
trace back to the test line where the skip
occurred
