Since 13cb41f666 PIPE_BIND_SHARED was used to allocate driver internal
video buffers. These buffers are never shared, but the intent was to
get non-suballocated buffers and SHARED was used as an indirect flag.
This commit switches to PIPE_BIND_CUSTOM which isn't used anywhere else,
and is now translated as "no suballocation".
The main benefit here is that this allows these buffers to set
use_reusable_pool to true reducing the CPU overhead a lot.
For instance, running the following command on my system:
ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi \
-i tears_of_steel_1080p.mov -an -c:v h264_vaapi output.mp4
takes 35 sec with this commit vs 45 sec without.
