Use ubuntu mirrors package for debian sources.list

[piraka9011]

Use the mirror protocol so apt selects the best mirror to use for downloading packages.
The default sources.list file used by colcon-bundle hardcoded the repo to the US mirror.
apt will now select the best mirror based on network and location.

Using the US repo on an instance in Tokyo, colcon bundle took 14m 59.416s.
Using the mirror protocol, bundling now takes 3m 47.402s

The mirror protocol does not work for Ubuntu Xenial (16.04) so we use the default archive repo instead of the explicit one from the US (which redirects to it's own mirror accordingly).

Using the mirrors results in the following error:

I can't reproduce locally on Ubuntu 18.04.

I was able to reproduce this in an ubuntu:xenial Docker image.
It looks like Xenial does not support the mirror protocol for apt.
