Summary: Updated automirror for urllib.request
Test Plan:
Verify basic function in US, but then also have non-US users test for functionality, especially paying attention to time.
More specifically, this patch should be able to be applied directly to /usr/lib/(i138-linux-gnu|x86_64-linux-gnu)/calamares/modules/automirror/main.py in a live system, then run the installer and see what happens.
