• Fixes a typo in labgrid-bound-connect, which should re-enable connection
  proxying for SSH.
• Man-Pages have been correctly regenerated.
• The exporter correctly handles the configured baud-rate for serial ports again.
• Various tests have been marked with skips if the modules are not available.
• Docker files have been moved to from the docker directory to the dockerfiles
  directory, which prevents the tests from incorrectly assuming a docker module
  is available.
