makefile: Add $(objutil)/kconfig/conf as make dependency

This patch fixes the build failure with 'make -j' where the build
fails at "$(MAKE)... savedefconfig" as that rule doesn't have the
dependency on kconfig/conf.

Normally make takes care of all dependencies, so parallel builds
work well. However if you have recursive make calls, i.e. make
calling make like in these recipes, there is no single make with a
global view of the dependencies anymore, and then multiple "makes"
can try to build the same file concurrently. Adding that explicit
dependency on build/util/kconfig/conf makes sure the recursive make
is only called later when the top-level make already finished
building build/util/kconfig/conf.
