Users setting up kernel module signing are instructed by our and upstream documentation to use the kernels x509.genkey config file. This ensures that
a supported key is generated.

However, in the current situation users will first have to emerge gentoo-sources or similar to actually get this genkey file. This is inconvenient
so lets just install the genkey config file in our dist-kernels.

There are also some other tools, scripts, and lists that may be useful, so while
we are changing this anyway lets just install all of those as well and in the process simplify the code.
