kconfig: Create include/generated for localmodconfig

If someone downloads a brand new kernel and runs localmodconfig or
localyesconfig, the ending result will report:

 *** Error during update of the kernel configuration.

This is because localmodconfig and localyesconfig must create the
include/generated directory to place the autoconf.h file.
