CI: set interface name in UPF container for RFSim5G

This MR addresses an issue related to CN deployment, observed in the RFSim5G CI pipeline. Specifically, the IP addresses within the UPF container were not consistently bound to the correct network interfaces. This inconsistency led to incorrect IP address assignments for the N3, N4, and N6 interfaces, resulting in connectivity issues.
