[libusb] libusb Wiki and libusb-win32 Wiki updated

[Xiaofan C. <xia...@gm...>]

It seems to me that there are always confusions about libusb and
libusb-win32 project. So I have updated the libusb project wiki (as
well as libusb-compat-0.1 project wiki). I have also updated the
libusb-win32 project wiki to say that is in bug-fix-only mode and new
project should migrate to libusb.

https://github.com/libusb/libusb/wiki
https://github.com/libusb/libusb-compat-0.1/wiki (very short version,
welcome to expand).
