upstream: When using a combination of a Yubikey+GnuPG+remote
forwarding the gpg-agent (and options ControlMaster+RemoteForward in
ssh_config(5)) then the codepath taken will call mux_client_request_session
-> mm_send_fd -> sendmsg(2). Since sendmsg(2) is not allowed in that codepath
then pledge(2) kills the process.
The solution is to add "sendfd" to pledge(2), which is not too bad considering
a little bit later we reduce pledge(2) to only "stdio proc tty" in that
codepath.
