Philipp Zabel af5acbc9cb libweston: let weston_output_update_capture_info() take drm_format
Let weston_output_update_capture_info() take a uint32_t drm_format
parameter directly instead of const struct pixel_format_info *format.
No other fields apart from the format were used from this structure.

Without this, callers may have to unnecessarily look up the pixel
format info in cases where the DRM fourcc is already available.
