Disable WritePriority test for v99.

This prepares for moving h3 priority from headers stream to control stream.

I don't think a new unit test for H3 priority is needed as frame encoding is well tested in http_encoder_test, and session Writev is well tested in quic_spdy_stream_test when h/3 headers are written.

gfe-relnote: test only change, not protected.
