libdrm 2.4.70 gets pulled in when intel-vaapi-driver is built because intel-vaapi-driver depends on intel-gpu-tools from backports, which in turn depends on a newer libdrm. I think I said this to you before: this is not a problem because the versions of libdrm at runtime will always be the same everywhere and intel-vaapi-driver does not seem to do anything different (as far as I'm aware) if built against a more recent version of libdrm.
