checkpatch: update image tag to latest

Update the tag for the checkpatch image in order to benefit from the
latest changes when running the GitHub action:

- Fix and update the issues reported by checkpatch.
- Allow for passing arguments directly to checkpatch.pl (not just the
  bash script), such as --fix-inplace.

See cilium/image-tools#85.
