util.stanza: Add method for extracting a single attribute value
Sometimes you only care about a single attribute, but the child tag
itself may be optional, leading to needing `tag and tag.attr.foo` or
`stanza:find("tag@foo")`.
The `:find()` method is fairly complex, so avoiding it for this kind of
simpler use case is a win.
