Remove unnecessary definition of _WIN64 in libpq/win32.mak.

In commit b0e40d1, I should have just removed the /D switch defining WIN64. The reason the code worked before is that all Windows64 compilers automatically predefine _WIN64. Perhaps at one time we had code that depended on WIN64 being defined, but it's long gone, and we should not encourage any reappearance. Per discussion with Christian Ullrich.
