mcpcontrol: policy based routing for INSTALLER_IP

To bypass Docker 'bridge'-backed network isolation, we previously
added an extra routing hop, which broke access from inside the
'mcpcontrol' Docker network (typically 10.20.0.0/24) to its
bridge address (10.20.0.1), leading to DNS issues on Salt Master.

This change leverages policy based routing to only add the extra
routing hop for connections originating from the default Docker
bridge network ('docker0'). Note that other Docker networks
using the 'bridge' driver are still isolated from 'mcpcontrol'.
