recipes-kernel: add kpatch dynamic kernel patching infrastructure

kpatch is a Linux dynamic kernel patching infrastructure
which allows you to patch a running kernel without
rebooting or restarting any processes

Currently it is enabled and tested on x86-64 systems,
although can be extended to PPC64 as well.
