kconfig: create directories needed for syncconfig by itself
'make syncconfig' creates some files such as include/config/auto.conf, include/generate/autoconf.h, etc. but the necessary directory creation relies on scripts/kconfig/Makefile. To make Kconfig self-contained, create directories as needed in conf_write_autoconf(). This change allows scripts/kconfig/Makefile cleanups; syncconfig can be merged into simple-targets.
