[erlang-patches] fix process leak in ssh_system_sup (dynamicaly created childs where not cleaned up)

[Niclas Eklund]

Hello!

Thanks for reporting this! I've added your patch and it will be included 
in R14B. I had to do some additional changes to avoid a race condition 
between some processes.

Best regards,

Niclas @ Erlang/OTP
