libs: encoder: h264: set the frame as IDR if forced key unit

Browse source 
GST_VIDEO_CODEC_FRAME_IS_FORCE_KEYFRAME() is a flag usually used to manage
the `frame-lost` event in the case of streaming, such as RTP.

In case of this event, it is needed to start new GOP rather than just
produce an I-frame.
