[CI] Don't restrict pre-commit for PRs from inside the repo

[aelovikov-intel]

If the PR's source branch is already inside origin then it is known to be safe.

You use sycl-devops-pr prefix for your test branch and we already allow running modified scripts for them. Right?

Yes, it's been described in PR/commit message for #10002.

Right. I don't think https://github.com/intel/llvm/pull/10441/checks really checks this change.

I think it does. Initially I've created the PR from a branch with the same name in my fork and its testing didn't start - see https://github.com/intel/llvm/pull/10440/checks.

But the goal of the change is to allow pre-commit for branches in intel/llvm, not for private forks. Isn't the goal of this change to enable pre-commit testing for LLVM pulldown PR? If so, we need to test it. IMO, negative testing is not enough and the use case from https://github.com/intel/llvm/pull/10441/checks should be already working.
