over-engineered thread-safe static OUString

This is a ridiculous over-engineered thread-safe static string for
something which is called so few times, and costs 1k of long-term
memory as the OUString dtor needs to be put into a callback
queue to get called at module unload time.

Just return a new string every time, *rolls eyes*
