Don't let psapi_new_instance trample libctx->stdio functions.
For GS builds this doesn't matter, as psapi_new_instance is called
before users of the API get to set their own versions. With GPDL
builds, the call to psapi_new_instance is deferred to the point
where the API user may have already set their own functions.
