fix process leak in ssh_system_sup (dynamicaly created childs where not cleaned up)
The ssh_system_sup supervisor supervises one ssh_subsystem_sup process for every client connection. There was no functionality to free resources (terminate_child/ delete_child) when a client connection was closed. Which lead to one ssh_subsystem_sup and one ssh_channel_sup process left over. This commit adds ssh_system_sup:stop_subsystem/2 and code that calls it in ssh_connection_manager:terminate/2.
