Nvidia driver does not build on Xenial LTS 4.15

[Modestas]

Please update the Nvidia 304 package so they can be built with the Xenial 4.15 lts kernel as is done on debian see:

https://packages.debian.org/jessie/nvidia-legacy-304xx-driver
https://metadata.ftp-master.debian.org/changelogs//non-free/n/nvidia-graphics-drivers-legacy-304xx/nvidia-graphics-drivers-legacy-304xx_304.137-0~deb8u1_changelog

  * Add nvidia-drm-pci-init.patch to fix kernel module build on Linux 4.14
    and newer (304.137-1).
  * Add timer.patch to fix kernel module build on Linux 4.15 and newer
    (304.137-4).

As now the driver is broken on Xenial LTS 4.15 only 4.4 works. As it is a LTS I hope this simple update will come soon. Thanks. :)
