In commit openembedded/openembedded-core@54ac820b8a, the packaging of
python3 base libraries changed. Amongst others, the packages,
python3-argparse, python3-subprocess and python3-textutils, are merged
into the python3 package.
Hence, this commit adjusts the runtime dependencies in the meta-ros
recipes accordingly.

The script environment_cache.py generates a cache file that
sets LD_LIBRARY_PATH so that the paths to target libs
go first. This confuses native python3 which dynamically links
to the target libpython3 and that leads to wrong linking
of dynamic python modules:

By default meta-ros uses python2. In case you want to get
python3-compatible builds add the following line to your local.conf:
ROS_USE_PYTHON3 = "yes"
