Walkthrough

This PR extends the kernel module blacklist configuration by adding three additional network-related modules: esp4, esp6, and rxrpc. The implementation modifies the system kernel modules setup script to install these modules to /bin/true, preventing them from loading. The change is accompanied by new RSpec test contexts that verify the blacklist file contains the correct entries for each module.
