Bump version to 0.1.9 after rebuild

Change-Id: I17dcecaa8d4fc2231aa72677c1caadf7a6d34db6
Add git-buildpackage conf and clean up a bit

- Since this is a deploy repo and not the source repo itself there is no
  problem with having the debian dir on master

- For our purposes a native package seems to be easier for now; can
  investigate moving to a non-native package with git-buildpackage later.

- remove .ex and .debhelper files
