Some necessary changes to build meta-ros with the current master 

This commit resolves issue #393.

catkin: patch _setup_util.py.in to address #384

Some hotfixes due to changes on the oe-core master branch

The svn version of log4cxx does not require the previous patches
and hence, they are dropped.

This patch fixes the continuous integration test by dropping
the sound-play recipe from ros-world, as it would fail with
the master branches (addresses issue #388).
