[PATCH 3/3] check-uapi: use dummy libc includes

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

Based on Thomas Weißschuh's series to kernel headers to no longer require
an installed libc when build testing the uapi headers, the same can now
be done for the scripts/check-uapi.sh script.

The only required change here is to add the  usr/dummy-include include
path.
