package/cog: add udev dependency to drm platform support
The DRM platform support already has the 'BR2_PACKAGE_HAS_UDEV' symbol in
package/cog/Config.in
We just need to specify 'udev' as a dependency in the cog.mk file.
The udev virtual package is pulled by libinput anyway, but this makes it
more explicit.
