recommended update for kiwi

This recommended update for kiwi fixes the following issues:
- Update to v7.01.18
+ Update .travis.yml to run for master only
+ Update .releasetags git helper tool to the master version
+ Update 13.2 JeOS description
* added less and iproute2 packages by default
+ Update 13.2 JeOS template
* added default network setup on lan0
+ Fixed use of rpm tools
* rpm has removed the db related options --initdb and --rebuilddb from the master rpm command. They are only available in the rpmdb command. Thus kiwi should better search for the rpm tool chain and decide for the commands to use according to their existence
+ Update source path in 13.2 JeOS image description
