Stop closing stderr and stdout streams (#8570)

Browse source 
Extensions may (and do) write to stderr in mshutdown and similar. In
the best case, with the stderr stream closed, it's just swallowed.

However, some libraries will do things like try to detect color, and
these will outright fail and cause an error path to be taken.
