Write udev rules during autoinstallation - bnc#787296

Udev rules (70-persistent-net.rule) wasn't written during
autoinstallation. It was excluded explicitly in Lan::Write.

Also added support for obsolete ID= attribute when detecting
device according rule from AutoYast profile. Customer uses it
and it is still supported in udev present in SLES11.
