Win32: preserving binary compatibility with Windows XP - Vista.

OpenSSL 1.1.0 and above uses BCrypt if available (Windows 7 or higher).
This results in an unusable binary on older Windows versions, when building
with newer Windows SDK (such as 7.0A).  Using CFLAGS to define _WIN32_WINNT
allows to set a desired ABI and make sure the binary works with Windows XP.

To not mix with other potential CFLAGS uses, it is set in GNUmakefile.
