Revert "removing all roscpp_core packages from the created ros source archive"

The commit 83c813b8 was due to an experiment
to cross-compile some packages and compile other on the target.
It turned out that there are a couple of difficulties and stopped working on
that experiment.
To obtain a working native compilation of ros-groovy,
this commit reverts the commit 83c813b8 to
a state where the installation and compilation worked.
