v4l2allocator: fix import_userptr() in single-planar API when n_planes > 1

Draft to check contiguity and size

As for the size calculation patch, we need video info to do our check, so I
move the code from allocator to bufferpool. And I exported a function from
gstv4l2object to extrapolate the v4l2 bytesperline to a specific stride.
