configure: define WIN32_LEAN_AND_MEAN early to make it effective

This macro makes windows builds faster and helps with the old "#define
interface struct" issue as the word "interface" is part of libusb-0.1
API. However, defining it in replacements.h is too late, as windows.h
gets included by that time from somewhere else.

This solution is provided by Ray Donnelly from the MSYS2 team.
