lib.ec.ssh.Paramiko: Close remote stdin

Prev Next 
_run_ssh() writes cmd_input to the remote stdin channel but never
closes the write side. The channel stays open until the client
process exits, so a remote command that reads stdin (cat, a login
shell, ...) never sees EOF and blocks forever - including for
cmd_input = None, which is supposed to mean non-interactive with
stdin from /dev/null.

Call shutdown_write() on the channel after writing the input, or
immediately when there is none, so the remote command gets EOF.
