scripts: net: Add SOCKS 5 to MQTT TLS sample test

Start SOCKS5 proxy in the net-tools Docker image and run MQTT TLS
tests with SOCKS enabled. Since the MQTT TLS server is already
running as of the previous test, start only the danted daemon.

Rely on mosquitto MQTT port being handled by the Docker image
configuration file instead of specifying it on the command line.
