HACK: Revert drm_format_modifier API back to the one used in our kernels

It looks like the modifier API is already present in upstream headers, as per
the libdrm commit below.

https://cgit.freedesktop.org/mesa/drm/commit/?id=7ec689a5406a4c5f468e126007c5aa9d72dd7f59

Moreover, it is binary-incompatible with the API used currently in ChromeOS,
added in following CL.

Since our kernels still use the old, incompatible API and transitioning
Chrome, one of the users, between incompatible interfaces have known to
introduce a lot of problems, let's temporarily revert back to the legacy
API.
