[PATCH 3/5] drm: Fix gcc warning about missing braces.

[Bryce Harrington]

Use double-brackets for config initializer for
create_output_for_connector to avoid gcc warning, since first
element is another struct.  (See GCC bug 53119.)

Quells warning:
  src/compositor-drm.c: In function ‘create_output_for_connector’:
  src/compositor-drm.c:2292:9: warning: missing braces around initializer
  [-Wmissing-braces]
    struct weston_drm_backend_output_config config = { 0 };
           ^
  src/compositor-drm.c:2292:9: warning: (near initialization for
  ‘config.base’) [-Wmissing-braces]
