avcodec/svt-av1: Set force_key_frames only when gop_size == 1

SVT-AV1 does not support requesting keyframes at arbitrary points
by setting pic_type to EB_AV1_KEY_PICTURE. So set force_key_frames
to 1 only when gop_size == 1.

Please see the comments in
https://gitlab.com/AOMediaCodec/SVT-AV1/-/issues/2076 for a bit more
details.
