[PATCH v3 2/2] services/tests: Retrieve monitor information when executed as service.

[Bernhard Übelacker]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=43187

Signed-off-by: Bernhard Übelacker <bernhardu at mailbox.org>

This patch is not merged with the previous one because there
is no todo_wine for service_ok.

Supersedes patch 152010.

v2:
- Fix test for wxppro or w2003.

v3:
- Test monitor handle.
- Test that callback got called just once.
- Test GetMonitorInfo with NULL HMONITOR.
- Test all bits of the dwFlags member.
