scripts: fix hop count detection for DEB822 sources with ports

The get-distro-has-hop-count-sources.sh script was failing when DEB822
format sources contained URLs with port numbers (e.g.,
eqpv-artifact.dtc.local:8081). The traceroute command requires just the
hostname without the port.

Fix by stripping the port number from the hostname using cut -d':' -f1
after extracting the domain from the URL. This ensures traceroute
receives a valid hostname regardless of whether the sources URL includes
a port specification.
