video/video-info: Don't use bool return of gst_video_info_set_format()/align() when running with GStreamer < 1.11.1

Browse source 
The bool return value was added in 1.11.1 and using the return value
with older versions gives a random value that might be true or false,
and then causes spurious errors.

Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/issues/236#note_399872
