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

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
