vcomp/lavc: h264_nvenc: fix pulsation w intra-refr

Browse Source 
Avoid pulsation with inra-refresh by repeating the missing SPS/PPS with
header inseter.

Unfortunately this is doesn't work well with HEVC because it seems that
the NVIDIA encoder keeps the reference almost forever in specific cases,
eg. `testcard:patt=text`. However, it _may_ work under some circumstances.
