samba: Modification to disable cups for samba build and install

- As discussed at IPFire conf call on 7th Oct
- disable cups for the samba configure stage
- Update of rootfiles
- Update of samba.cgi to remove the printing of a printer share into the samba
   configuration file.
- Tested out on vm system. Installed samba with only avahi, perl-Parse-Yapp, perl-JSON
   and wsdd as dependencies. Installed without any problems. Existing share was able
   to be accessed without any problems and a new share was created and was also able
   to be accessed without problems.
