Make progressive renderer default for pdfium_test.

When Chrome renders PDF pages it uses the progressive renderer. The one
shot renderer is used to render print preview pages. This CL changes
pdfium_test to use the progressive renderer by default to better match
Chrome. This also adds a --render-oneshot flag which will use the
non-progressive renderer.
