Fix coreboot project-specific pre-upload hooks

- Coreboot is now a public repo, and is named
  "chromiumos/third_party/coreboot", not "chromeos...".
- Add Signed-off-by presubmit check, since it's a requirement upstream.
- Branch only: Remove BRANCH= check since we're already a branch, and
  remove copyright check because we don't have the file exclusion rules
  setup correctly. Need to investigate how to do that.

BUG=chromium:338878
TEST=Verified that coreboot commit without sign-off was caught by presubmit.
Verified that adding sign-off allowed presubmit pass.
