lavc/libx265: Use avctx->framerate first for frame rate setting

Browse Source 
perfer avctx->framerate first than use avctx->time_base when setting
the frame rate to encoder. 1/time_base is not the average frame rate
if the frame rate is not constant, so use avctx->framerate if the
value is not zero.
