util/kconfig: Uprev to Linux 5.16's kconfig

Browse Source 
Linux 5.16 saw a significant rewrite in the boolean handling which
reduces our change set. On the other hand, it's all new code.

Comparing the config.build and config.h files generated by
`util/abuild/abuild -C`, only a few lines of comment in the header
changed.

commit 7b2deddbb0ef350e189fe42c025b07c943aedc4c
Author: Raul E Rangel <rrangel@chromium.org>
Date: Thu Jul 25 15:49:52 2019 -0600
Kconfig: Write tmp files into same directory as target files
This removes the need for COREBOOT_BUILD_DIR in Kconfig. Since the
original files will be replaced with the tmp file, the parent directory
already needs to be writable.
Before this change, the tmp files would be created in the CWD (src) if
COREBOOT_BUILD_DIR was not specified.
BUG=b:112267918
TEST=emerge-grunt coreboot and verified no tmp files were created in the
src directory.
