update autoyast for SLES 12 and OpenSuSE 13

some updates to the autoyast templates, tested and working with:
- SLES 11 SP3
- SLES 12
- OpenSuSE 13.1
- OpenSuSE 13.2

On OpenSuSE 11.4 (really EOL now: http://www.rosenauer.org/blog/2014/09/27/opensuse-11-4-has-reached-end-of-evergreen-support/) installing with Puppet seems to trigger a bug and one has to press "OK" one time.

On OpenSuSE 12.3 (EOL 2015-01-04), bug 801878 (https://bugzilla.novell.com/show_bug.cgi?id=801878) is triggered, I'm not sure if that should taken into account or not...
