kconfig: fix failing to generate auto.conf
[ Upstream commit 1b9e740a81f91ae338b29ed70455719804957b80 ]
When the KCONFIG_AUTOCONFIG is specified (e.g. export \
KCONFIG_AUTOCONFIG=output/config/auto.conf), the directory of
include/config/ will not be created, so kconfig can't create deps
files in it and auto.conf can't be generated.
