avcodec/audiotoolboxenc: remove CAP_VARIABLE_FRAME_SIZE from alac 

AV_CODEC_CAP_VARIABLE_FRAME_SIZE has been set for alac_at encoder,
which means avctx->frame_size should be zero. However, alac_at
encoder also set avctx->frame_size. This leading to assert failure
in ffmpeg_sched.c
	av_assert0(enc->sq_idx[0] >= 0);

Actually, the implementation of audiotoolboxenc.c doesn't support
frame_size been zero.

Fix #10720.
