jws: add EncodeWithSigner function.

This permits controlling the mechanism for signing the token;
for instance, one can use EncodeWithSigner in an App Engine app
to use the App Identity API to perform the signing (you don't have
direct access to the private key there).

An alternate would be to replace Encode with EncodeWithSigner,
and add a little wrapper type that turns a *rsa.PrivateKey into
a Signer. That's probably what I'd do if this were being written
from scratch, but I wasn't keen on breaking existing code.
