OpenSSH: Update to 10.3p1

Full release notes are available at
https://www.openssh.com/txt/release-10.3

Selected highlights from the release notes:

* ssh(1), sshd(8): remove bug compatibility for implementations
that don't support rekeying. If such an implementation tries to
interoperate with OpenSSH, it will now eventually fail when the
transport needs rekeying.

* ssh(1), sshd(8): support IANA-assigned codepoints for SSH agent
forwarding, as per draft-ietf-sshm-ssh-agent. Support for the new
names is advertised via the EXT_INFO message. If a server offers
support for the new names, then they are used preferentially.

* ssh(1): add a ~I escape option that shows information about the
current SSH connection.

* sshd(8): add 'invaliduser' penalty to PerSourcePenalties, which is
applied to login attempts for usernames that do not match real
accounts. Defaults to 5s to match 'authfail' but allows
administrators to block such attempts for longer if desired.

* Support the ed25519 signature scheme via libcrypto.
