if we had this line in ContentBrowserTest::Setup, would we still need the change
in the other ppapi_test.cc (chrome) and webrtc browser test file?

Not sure, I'll investigate.  I tried to limit the scope of the change to only
the tests that explicitly needed it but maybe it makes more sense to go up to a
higher level such as ContentBrowserTest.
