cppumaker: Allow UNO interface functions to throw std::exception

...so that exceptions like std::bad_alloc need not be treated in C++
implementations of UNO interfaces to not cause std::unexpected.  Of course, this
requires implementations to be adapted and actually mention std::exception in
their exception specifications.
