test: Improve loopback address check in rcp_bind.py

Browse Source 
A loopback address can range from `127.0.0.0` to `127.255.255.255`.
This commit relaxes the loopback check in `rpc_bind.py` by checking whether
an IP address (from `all_interfaces()`) starts with `'127.'` instead of
strictly matching `'127.0.0.1'`.

Programs like VPNs might add an extra loopback address (e.g., 127.1.130.83),
which failed under the previous state. These addresses will now pass with this update.
