The class-loader package fails if the pre-built binary of Poco
library is used. The PocoFoundationTargets.cmake file coming
with the pre-built binary have hardcoded paths to libz and libpcre
which makes the cross-compilation to fail.
This fix removes Poco library from the apt-get list and forces
to build it inside the poco_vendor ros2 packages.
