Make PRESUBMIT.py accept SkiaPaths expected results.

Using Skia and using SkiaPaths sometimes lead to different rendering
results. For a pixel/corpus test case, if both Skia's and SkiaPaths'
rendering results are acceptable, a SkiaPaths specific expected result
is needed for this test case besides its Skia expected result.

This CL modifies PRESUBMIT.py to accept SkiaPaths specific expected
results with names in the form of
"NAME_expected_skiapaths(_(win|mac|linux))?.pdf.#.png", adds a
test for _CheckPNGFormat() and hooks up the test to run as part of the
presubmit process.
