scripts/contrib: scripts that updates kernel templates

Updating the kernel templates (those use by the yocto-bsp script) is a mechanical
process (and prone to errors) which consists of copying latest kernel template then
applying string replacements from old to new kernel version. This script collects
these commands allowing quick updates in the future.
