mirrors: rationalise Debian mirrors

Change DEBIAN_MIRROR to point at the canonical server, deb.debian.org.

This is a CDN-backed server using network magic to load balance across
the planet so there's no need to set a slew of regional mirrors.

Also add a more recent snapshot.debian.org from the beginning of 2025.
