setupapi: Add tests for dirid values.

[Vincent Povirk]

This was written with the intent of eliminating a CrossOver hack for
the undocumented dirid 13 (used by the IE6 installer), however
winetestbot showed
(https://testbot.winehq.org/JobDetails.pl?Key=16871) that not all
Windows versions understand this id. Still, it doesn't hurt to
increase our test coverage.
