[Bug 36155] valgrind shows a leak whenever using a virtual desktop

https://bugs.winehq.org/show_bug.cgi?id=36155

--- Comment #1 from Austin English  ---
In wine-4.3-229-g6d82b2f1ad, I'm seeing this in tests without a virtual desktop
enabled

(at least, valgrind shows it being suppressed):
==18146== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 702 from 5)

(though the suppression may be too wide, currently it's just looking for leaks
that contain xinerama_init()).
