kbuild: remove cc-name variable

There is one more user of $(cc-name) in the top Makefile. It is supposed to detect Clang before invoking Kconfig, so it should still be there in the $(shell ...) form. All the other users of $(cc-name) have been replaced with $(CONFIG_CC_IS_CLANG). Hence, scripts/Kbuild.include does not need to define cc-name any more.
