Checkout commit for customer_testing

The `GIT_BRANCH` is `master` for both pre-submit and post-submit. This is okay for post-submit as we are validating TOT, but it fails to validate PR changes for pre-submit. This CL does
1) Checkouts latest commit instead of branch `master`
2) No-op for release branches
