ci: fix saucelabs_view_engine master-only failing (angular#34429)

Currently the `saucelabs_view_engine` job fails because
the Saucelabs Bazel run script thinks that `--config=saucelabs`
is a flag targeting the actual script. This is not the case and
the flag should be actually part of the bazel command.

PR Close angular#34429
