gtk: avoid redefining _WIN32_WINNT macro

When building for Mingw64 target on Fedora 22 a warning
is issued about _WIN32_WINNT being redefined.

In file included from ui/gtk.c:40:0:
include/ui/gtk.h:5:0: warning: "_WIN32_WINNT" redefined
 # define _WIN32_WINNT 0x0601 /* needed to get definition of MAPVK_VK_TO_VSC */
  ^

 #define _WIN32_WINNT 0x502
 ^

Rather than try to get MAPVK_VK_TO_VSC defined indirectly
by defining _WIN32_WINNT, instead just define it explicitly
if missing.
