[Buildroot] [git commit branch/2022.05.x] package/cog: add libgbm as dependency when building with DRM support

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=c25e77eec5738b31aa6093410b5745d9939844b7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.05.x

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.
