Upload all logs in BEP even with minimal upload

When using --experimental_remote_build_event_upload=minimal, build
action logs won't get uploaded. These logs are still very useful as when
a build action fails, one would need to inspect them to figure out what
has gone wrong. Forcing uploading stdout and stderr with this change.
