Bug Description

mirrord panics when run with ruby ( a simple web server)

Steps to Reproduce

mirrord exec -t pod/py-serv-deployment -c -- ruby test.rb

require 'socket'

server = TCPServer.new 8080

while session = server.accept
  request = session.gets

  puts request

  response = "HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\n\r\nHello, world!"
  session.print response

  session.close
end

This seems to be similar to #848 since explicitly specifying (server = TCPServer.new("127.0.0.1", 8080) or server = TCPServer.new("::1", 8080)) the address works but when not specified (server = TCPServer.new 8080) it panics
