Nick Terrell 49a9e070f5 [contrib][linux-kernel] Update test include stubs

Update the test include stubs so they are able to run the current zstd
version in the kernel, so I can compare stack usage.

Zstd in the Linux Kernel

This directory contains the scripts needed to transform upstream zstd into the version imported into the kernel. All the transforms are automated and tested by our continuous integration.

Upgrading Zstd in the Linux Kernel

cd into this directory.
Run make libzstd and read the output. Make sure that all the diffs printed and changes made by the script are correct.
Run make test and ensure that it passes.
Import zstd into the Linux Kernel make import LINUX=/path/to/linux/repo
Inspect the diff for sanity.
Check the Linux Kernel history for zstd. If any patches were made to the kernel version of zstd, but not to upstream zstd, then port them upstream if necessary.
Test the diff. Benchmark if necessary. Make sure to test multiple architectures: At least x86, i386, and arm.
Submit the patch to the LKML.
