rtc: Fix to frame_type setting for 1 pass rtc

Set the cm->frame_type in av1_get_one_pass_rt_params,
since its used in cyclic refresh which is called before
av1_encode (where cm->frame_type is currently set).

This will allow the refresh to start on the first
frame following the key frame, as it was intended.

Negligible change in psnr/ssim metrics or fps.
Update in PSNR in rt_end_to_end_tests.
