[h264e]: Add gaps in frame_num config entry

Browse Source 
Some of NVR product may do some thing special when decoding the first
GOP of bitstream encoded by MPP, and report "gaps in frame_num is not
allowed" although frame_num is bitstream is continuous. Setting
gaps_in_frame_num_allowed_flag to true will avoid this problem.

1. Set gaps_in_frame_num_allowed_flag true as default
2. call mpp_enc_cfg_set_u32(cfg, "h264:gaps_not_allowed", 1) if you
want gaps_in_frame_num_allowed_flag to be false.
