provisioning: do not install libc++ on ubuntu

installing libc++-20-dev and libgstreamer1.0-dev on the same system
causes problems:
* using the llvm apt repo, it will uninstall libgstreamer1.0-dev
* using ubuntu's repo, it will break gstreamer's pkg-config integration

reason is that libgstreamer1.0-dev depends on libunwind-dev, but llvm's
libunwind-20-dev does not provide the pkg-config files.
as temporary workaround we basically revert
e5b56d1d37.
