Currently, kheaders_data.tar.xz contains some build scripts as well as
headers. None of them is needed in the header archive.
For ARCH=x86, this commit excludes the following from the archive:
arch/x86/include/asm/Kbuild
arch/x86/include/uapi/asm/Kbuild
include/asm-generic/Kbuild
include/config/auto.conf
include/config/kernel.release
include/config/tristate.conf
include/uapi/asm-generic/Kbuild
include/uapi/Kbuild
kernel/gen_kheaders.sh
This change is actually motivated for the planned header compile-testing
because it will generate more build artifacts, which should not be
included in the archive.

The -R option of 'ls' is supposed to be used for directories.
-R, --recursive
list subdirectories recursively
Since 'find ... -type f' only matches to regular files, we do not
expect directories passed to the 'ls' command here.
Giving -R is harmless at least, but unneeded.

Linus reported an issue that doing an allmodconfig was causing the
kheaders archive to be regenerated even though the config is the same.
This patch fixes the issue by ignoring the config-related header files
for "knowing when to regenerate based on timestamps". Instead, if the
CONFIG_X_Y option really changes, then we there are the
include/config/X/Y.h which will already tells us "if a config really
changed". So we don't really need these files for regeneration detection
anyway, and ignoring them fixes Linus's issue.

The kheaders archive consisting of the kernel headers used for compiling
bpf programs is in /proc. However there is concern that moving it here
will make it permanent. Let us move it to /sys/kernel as discussed [1].
