procutil: move stdin assignment outside of try-finally block There is an stdin variable in the global scope of this module. And in the `finally` block of this try-finally statement we're checking `if stdin is not None`. Let's make sure we don't confuse code check tools into thinking we want to use global stdin by moving this line of code outside of `try`. This was caught by pytype 2023.11.21 on Python 3.11.2.

zeroconf: give inet_aton() str instead of bytes All other uses of this function in this extension are already fixed (i.e. use strings instead of bytes). This was caught by pytype 2023.11.21 on Python 3.11.2.
