sshrsa.c now obeys the RFC793 Robustness Principle when it comes to
the ordering of the primes in a fully specified RSA private key:
when the key format typically has p > q, it will always output p > q
but be willing to tolerate p < q on input. (Inspired by seeing an
OpenSSH-format key file in the wild which had p < q, which I've
never seen before; I suspect a third-party application incautiously
generating the format.)
