RFR: 8219920: dependency help output in configure-step : support zypper tool

[Baesken, Matthias]

Hello, please review the following  change .

Currently  the  configure-step  outputs  help  for  a number of  packages + related installation calls  in case of missing dependencies  (like cups / alsa etc.) .
This help output step   covers a few  tools (like apt-get).


However the OpenSUSE / SLES tool zypper  is not supported .
This  change adds  output for  zypper .
