doc/SubmittingPatches: correct subject guidance

The examples and common practice for adding markers such as "RFC" or "v2" to the subject of patch emails is to have them within the same brackets as the "PATCH" text, not after the closing bracket. Further, the practice of `git format-patch` and the like, as well as what appears to be the more common pratice on the mailing list, is to use "[RFC PATCH]", not "[PATCH/RFC]". Update the SubmittingPatches article to match and to reference the `format-patch` helper arguments, and also make some minor text clarifications in the area.
