When building with the DRM support, it can happen that the libgbm library
is not yet built by the provider of this lib (specified by
BR2_PACKAGE_PROVIDES_LIBGBM).
The docs in cog `docs/platform-drm.md` specify this dep-list:
- **WPEBackend-fdo**:
- **Wayland**:
- **libdrm**:
- **libgbm**:
- **libinput**:
- **libudev**:
libgbm needs to be added.
Adding libegl as well.
Updated package/cog/Config.in to define the dependencies (for DRM)
according to libegl & libgbm.
