Make user32/win.c tests pass on Win9x and NT platforms

[Dmitry Timoshkov]

Hello,

Changelog:
    Dmitry Timoshkov <dmitry at codeweavers.com>
    - Skip shell window test on Win9x and restore its functionality
    on NT platforms.
    - Use keybd_event instead of SendInput in order to perform keyboard
    input test on Win95 as well.
