smoothstreaming: update fps calculation for h264 codec parser API changes

Use new gst_h264_video_calculate_framerate() API instead of fps_n/fps_d
fields in SPS struct which are to be removed.

Apparently H264 content in MSS is always non-interlaced/progressive,
so we can just pass 0 for field_pic_flag and don't need to parse any
slice headers first.

I'm only 90% sure that page allows us to conclude things about MSS though, but
one would suspect some other kind of external signalling for
interlaced/non-interlaced in any case then.
