Only change aria-pressed if it's not an input-based radio or checkbox group

aria-pressed="true"/aria-pressed="false" is really only useful for making on/off toggles out of, say, <button> elements. the attribute is useless (and potentially confusing/conflicting) on, say, <label> elements for an existing <input type="radio"> or similar.
