Bug Description

The python3-lttngust package contains bindings that use ctypes to interact with a dedicated library provided by the liblttng-ust-python-agent0. The python code loads the library by name but it targets the un-versioned ".so" which is part of the dev package.

This means that when installed without the dev package the bindings won't work.

The fix is to load the library by name and use the SONAME version ".so.0".

I'll provide a debdiff for the affected versions.
