fftools/ffmpeg: make specifying thread_queue_size turn on threaded input

Browse Source 
Threaded input can increase smoothness of e.g. x11grab significantly. Before
this patch, in order to activate threaded input the user had to specify a
"dummy" additional input, with this change it is no longer required.
