[PATCH] rtworkq/tests: Load CoGetApartmentType() dynamically.

[Francois Gouget]

The main goal is to get WineTest reports to state that the test was
skipped because rtworkq.dll is missing rather than because of a
possibly unrelated API.

Restating differently, currently looking at a WineTest report (or
test.winehq.org) I see that the test was skipped on Vista because
of a missing API and I am left to guess whether rtworkq.dll was
available at all.

This patch takes out the guessing part even if nothing can be tested 
(so far).
