The shim review board (which is the secure boot base loader) recommends using ephemeral keys when signing the Linux Kernel. This commit enables the Kernel build system to generate a one-time ephemeral key that is used to: * sign all build-in Kernel modules * sign all other out-of-tree Kernel modules The key lives in /tmp and is destroyed after the build container exits and is named: "VyOS build time autogenerated kernel key". In addition the Kernel now uses CONFIG_MODULE_SIG_FORCE. This now makes it unable to load any Kernel Module to the image that is NOT signed by the ephemeral key.
