TT#21905 Switch lua-ngcp-kamailio Dockerfile to Debian stretch

+ TT#22410 Fix typo in Dockerfile 'Instructions for usage'

In jessie based docker we used lua-unit 3.0-1 while in stretch it is
3.2-1. Newer lua-unit doesn't have setFname and setVerbosity functions.
Instead of setFname we can use --name parameter. setVerbosity(1) is set
by default so we can simply omit it.
