mkksiso: Add a tool to add a kickstart to an existing boot.iso
This tool will add the kickstart to the boot.iso, edit the kernel boot arguments so that the kickstart is used when the iso boots, as well as allow adding extra files and directories to the / of the iso which can then be used by the kickstart (they are found under /run/install/repo while Anaconda is running).
