agent: Not remove SSH socket when already running.

[NIIBE Yutaka]

Hello,

I tried to push my changes to master, and I found another problem.
When SSH support is enabled and gpg-agent is already running, the
socket for SSH will be removed.  (And I can't use SSH.)

This is obvious bug and simple fix, so, I'm going to push this.

    * agent/gpg-agent.c (main): Defer setting of socket_name_ssh to avoid
    removal of the socket when it will die in create_server_socket for
    socket_name.
