[Libosinfo] [osinfo-db PATCH 2/2] install-script, rhel: Only add install-source if there's an install URL

[Fabiano Fidêncio]

When dealing with net-install ISOs, we may reach the situation where
the command-line template will generate the command-line adding a
"inst.repo=" but the installation URL is not present.

The easiest way to deal with this is checking whether an installation
URL is present and only adding "inst.repo=" if that's the case.
