[PATCH 11/19] kconfig: move .kernelrelease

[Roman Zippel]

This moves the .kernelrelease file into include/config directory.
Remove its generation from the config step, if the config step doesn't
leave a proper .config behind, it triggers a call to silentoldconfig.
Instead its generation can be done via proper dependencies.
