Subject: util/kconfig: add olddefconfig target

There doesn't seem to have been an olddefconfig target in the coreboot
version of the Kconfig makefile.  It's listed in the .PHONY, but it
doesn't seem like it's ever been there.  This is useful for expanding
a miniconfig saved with 'make savedefconfig'.
