Sonar: report correct test coverage (by using a build that does not use pack200)

Currently our Sonar instance erroneously reports our test coverage with 0.8%

According to lheinema@redhat.com this is caused by the fact that we build using pack200. In Fuse Tools they added a build in jenkins just for sonar, which is NOT using pack200 and their sonar analysis therefore reports their test coverage more accurately at 29%
