Add kernel header update script
This helper pulls the required kernel headers for KVM and vhost into a
specified directory. The update is triggered via
scripts/update-linux-headers.sh LINUX_PATH
and will place the output under linux-headers/linux and linux-headers/asm-*.
It also imports the COPYING to care for headers without an explicit license.
