torture_channel_exit_signal test hang intermittently

We started noticing that torture_channel_exit_signal hangs intermittently on all platforms, I'm also able to reproduce this in tumbleweed with some degree of success (1 in 10 runs).

The issue seems that the server dies before the client can read the exit status, setting a timeout (patch below) fixes the issue.

Also, I'm not sure if exit_status if set correctly, note that assert_ssh_return_code(session, rc); is the previous value from rc = ssh_channel_request_send_signal(channel, "TERM");.
