[PATCH 10/13] kconfig: move default KBUILD_DEFCONFIG back to scripts/kconfig/Makefile

[Masahiro Yamada]

This is a partial revert of commit 2a86f6612164 ("kbuild: use
KBUILD_DEFCONFIG as the fallback for DEFCONFIG_LIST").

Now that the reference to $(DEFCONFIG_LIST) was removed from
init/Kconfig, the default KBUILD_DEFCONFIG can go back home.
