procutil: assign pseudo file object if sys.stdout/stderr is missing

This basically simulates the Python 2 behavior. If libc stdio were used,
these file objects would be available and raise EBADF. There is subtle
difference between py2 and py3, but I think py3 behavior (i.e. exit 255)
is more correct.

"if" conditions are adjust so that they look similar to
dispatch.initstdio().
