Subject: [PATCH] x11: Add call to XInitThreads()

The Mesa Vulkan drivers need XInitThreads() being called, because their
implementation has to use threads.

And I don't want to make the call depend on if Vulkan is compiled in
because that makes GTK's X11 behavior depend on compile-time flags, so
it's always called.
