tdf#104830, need an own termination listener for lib objects
The destruction of the SwDLL object happens already through the normal
termination listener but the other termination listeners might still
depend on it. Also the outstanding events might need the SwDLL instance
to be still around.
This makes the destruction of the instance explicit and at a time when
it should be safe. We should use the same code for calc, impress, math
and base as well.
