Add support for passing an fd to the user's S/Key record back and

forth between login_skey and the invoking process.  This allows us
to keep the record locked between an invocation of login_skey that
receives the challenge and another that verifies the response,
preventing an interloper from sniffing the challenge and beating
the legitimate user to the response.
