check_ssh_login plugin incorrectly handles configured timeout

[atc0005]

Overview

By default the plugin is configured with a 10 seconds timeout intended to prevent connection attempts from hanging.

Today one the systems monitored by a Nagios XI system I manage went down and Nagios XI ended up forcefully terminating the service check after 300.01 seconds (300s global timeout value).

This looks to be a repeat of GH-179 (which was believed resolved per GH-188).
