test: libtest: buffer_source: Close video device right after allocation

Browse source 
There's no need to keep the video device open after allocating buffers,
as V4L2 supports buffer orphaning and the exported buffers will still be
usable. Close the device right after allocation to avoid the need for
delayed cleanups.
