kbuild: save overridden KERNELRELEASE in include/config/kernel.release
Commit Message
${KERNELRELEASE} is used as a part of the installation path.
(INSTALL_DTBS_PATH, MODLIB, etc.)
When KERNELRELEASE is overridden from the command line, it should be
saved in include/config/kernel.release, so that it will be consistently
used for the installation steps.
