Win32: Suppress tautological const compare warning

Suppress a warning due to an always-false (on 64-bit Windows)
conditional expression that is being used as an architecture check.

    ../../third_party/libpng/png.c(2567,8): warning: result of comparison of
    constant 2305843009213693944 with expression of type 'unsigned int' is
    always false [-Wtautological-constant-out-of-range-compare]
       if (png_gt(((width + 7) & (~7U)),
    ../../third_party/libpng/png.c(2543,29): note: expanded from macro 'png_gt'
    #define png_gt(a,b) ((a) > (b))
                         ~~~ ^ ~~~
