[PATCH] checkpatch: Use python3 to run spdxcheck.py

[Paul Barker]

Since commit d0259c42abff ("spdxcheck.py: Use Python 3"), the shebang
line in scripts/spdxcheck.py says the script should run with `python3`.
However, checkpatch has been explicitly running this script with
`python` so it needs updating to ensure that Python 3 is used on all
distros.
