ssh: update to OpenSSH 9.1p1

Release notes are available at https://www.openssh.com/txt/release-9.1

9.1 contains fixes for three minor memory safety problems; these have
lready been merged to the copy of OpenSSH 9.0 that is in the FreeBSD base
system.

Some highlights copied from the release notes:

Potentially-incompatible changes
--------------------------------

 * ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config
   are now first-match-wins to match other directives. Previously
   if an environment variable was multiply specified the last set
   value would have been used. bz3438

 * ssh-keygen(8): ssh-keygen -A (generate all default host key types)
   will no longer generate DSA keys, as these are insecure and have
   not been used by default for some years.

New features
------------

 * ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum
   RSA key length. Keys below this length will be ignored for user
   authentication and for host authentication in sshd(8).

 * sftp-server(8): add a "users-groups-by-id@openssh.com" extension
   request that allows the client to obtain user/group names that
   correspond to a set of uids/gids.

 * sftp(1): use "users-groups-by-id@openssh.com" sftp-server
   extension (when available) to fill in user/group names for
   directory listings.

 * sftp-server(8): support the "home-directory" extension request
   defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps
   a bit with the existing "expand-path@openssh.com", but some other
   clients support it.

 * ssh-keygen(1), sshd(8): allow certificate validity intervals,
   sshsig verification times and authorized_keys expiry-time options
   to accept dates in the UTC time zone in addition to the default
   of interpreting them in the system time zone. YYYYMMDD and
   YYMMDDHHMM[SS] dates/times will be interpreted as UTC if suffixed
   with a 'Z' character.

   Also allow certificate validity intervals to be specified in raw
   seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This
   is intended for use by regress tests and other tools that call
   ssh-keygen as part of a CA workflow. bz3468

 * sftp(1): allow arguments to the sftp -D option, e.g. sftp -D
   "/usr/libexec/sftp-server -el debug3"

 * ssh-keygen(1): allow the existing -U (use agent) flag to work
   with "-Y sign" operations, where it will be interpreted to require
   that the private keys is hosted in an agent; bz3429
