On Windows (MSYS2), hidapi is used instead of hidapi-hidraw. This PR avoids the need to specify it when calling make. So, make works instead of make HIDAPI=hidapi.
At the same time, LIBUSB_CFLAGS, LIBUSB_LIBS, HIDAPI_CFLAGS and HIDAPI_LIBS seems unnecessary, because those are used in a single place.
