resourceutil: force filesystem access to resources when using py2exe
I don't know why it doesn't work, but it avoids this fatal error on startup:
> hg debugshell
Traceback (most recent call last):
File "hg", line 58, in <module>

AssertionError
I assume the py2 version of py2exe never hit this because `importlib.resources`
failed to import.
