Fix process execution on Windows 7

Browse Source 
According to this bug report on Firefox:
<https://bugzilla.mozilla.org/show_bug.cgi?id=1460995>

> CreateProcess fails with ERROR_NO_SYSTEM_RESOURCES on Windows 7. It
> looks like the reason why is because PROC_THREAD_ATTRIBUTE_HANDLE_LIST
> doesn't like console handles.

To avoid the problem, do not pass console handles to
PROC_THREAD_ATTRIBUTE_HANDLE_LIST.
