Makefile.inc: Add dependency on util/kconfig/conf for config.h

This dependency wasn't called out before, and when building with enough
    threads, the build would fail due to a collision trying to build
    build/util/kconfig/conf.

Fixes this failure:
    make[1]: execvp: build/util/kconfig/conf: Permission denied
    /home/martin/git/coreboot/util/kconfig/Makefile:40: recipe for target
    'oldconfig' failed
    make[1]: *** [oldconfig] Error 127
    Makefile:167: recipe for target 'build/config.h' failed
