We missed a case in testing releases because the release-test repo did
not require having a CLA signed. The release-tools and release-test
repos share an ACLs file. Rather than split the ACLs, just update the
release-tools ACLs in place to add the flag so that future tests more
accurately reflect what real repositories will look like.
