It seems that LO_TESTNAME name is currently not set on Windows (or that
is my reading of sal/cppunittester/cppunittester.cxx).

I’m rather not sure if we want to do this unconditionally for all tests
or not, but if that is the consensus, I think we can make sure
LO_TESTNAME is set also on Windows (assuming there is no reason not to
do so) and use it.
