Really set 'latest_builds' to the latest value of the day

Consider the following scenario:

System being set-up on day 0 (by running user-setup.sh script)
The github.com/clearlinux/common repo is cloned under projects/common
Fast-forward in the future
Clone a package for which there is no reachable upstream URL (e.g. clr-power-tweaks or clr-systemd-config
Run 'make sources' That operation will fail because it will search for the src.rpm files starting with the Clear Linux build determined by looking up the latest tag in the project/common repo (and the latest is the one from day 0). So it will only find older versions of those src.rpm, and will eventually fail.

This patch adds a line that fetches all the latest tags from the upstream projects/common repo so the 'latest_builds' variable is really set to the latest of the day.
