user32: Button should lose highlighting on focus loss

[Nikolay Sivov]

You could easily reproduce this issue:
    - highlight any checkbox with space key
    - keep space pressed and changed focus (with arrows or tab)
After that checkbox will be unfocused but still highlighted wich is a bug.
The same applies of course to radiobuttons too.

Changelog:
    - Button should lose highlighting on focus loss
