[graphics][graphics_drivers] Build NVIDIA kmod

[LukeShortCloud]

Instead of providing an akmod package for client-side builds, explain how to use a kmod package for server-side pre-builds. NVIDIA has made a few open source projects to help assist with this.

Some observations of using the yum-packaging-precompiled-kmod script:

• A GPG key is required. If no keys are detected, one will be generated. A password prompt will appear for this.
• The kernel version information for the kernel-devel package to install is pulled from uname meaning it matches whatever the build OS is using:

# Kernel defaults
kernel=$(uname -r | awk -F '-' '{print $1}')
release=$(uname -r | awk -F '-' '{print $2}' | sed -r 's|\.[a-z]{2}[0-9]+| |' | awk '{print $1}')
dist=$(uname -r | awk -F '-' '{print $2}' | sed -r -e 's|\.[a-z]{2}[0-9]+| &|' -e "s|\.${arch}||" | awk '{print $2}')

• Only specific driver versions can be re-used as a handful of packages are repacked.
