[JENKINS-48294] GitHubSCMBuilder does not respect clone depth parameter in pull requests

Trying to build a pull request on my github repo and facing with build failure due to timeout.

I've set shallow clone depth option to 1, but the log shows that "--depth" parameter is missing. Seems like that option is respected in branches only.

So, git is trying to do a full repo clone, which is currently 600 MB. Able to workaround that by setting a 1 hour timeout, But that's absolutely insane: just to assure that a pull request is fine, I have to wait for an hour to start the check script.

Probably, related to -JENKINS-45771-, maybe a separate shallow clone options would be more preferrable rather than ignoring it for some weird reason.
