Add defaults for CUPSADMIN and CUPSPASSWORD

Browse Source 
If the variables CUPSADMIN and/or CUPSPASSWORD are not provided on start
adding the cups admin will fail, but the container will nevertheless
start.

With this change CUPSADMIN - if missing - will be set to "cupsadmin" and
CUPSPASSWORD - if missing - will be set to the name of the cups admin.
