user[1/5]: add SPI_{GET,SET}DESKWALLPAPER tests

[Andrew Ziem]

This section of tests passes on Windows 2000.  Also, the tests fail on 
Wine until the other patches in the set are applied; then, all the tests 
in the section pass.

These set of 5 patches are updated based on comments from Andrey Turkin 
after original post:
