Properly include current libusb-win32 header

libusb-win32 is using a different header file name (lusb0_usb.h) for
a while. Use that on Windows builds to make clear that this is
currently the correct header to include.

Hopefully this will change soonish by migrating away from libusb-0.

Corresponding to flashrom svn r1877.
