libusb commit f0cce43f882d ("core: Fix definition and use of enum
libusb_transfer_type") split the types of split transfer type and
endpoint transfer, introducing LIBUSB_ENDPOINT_TRANSFER_TYPE_BULK.
The result is that when building with older libusb, such the one
available on Ubuntu 20.04 the build fails with the following error:
usb.c:84:16: error: ‘LIBUSB_ENDPOINT_TRANSFER_TYPE_BULK’ undeclared (first use in this function); did you mean ‘LIBUSB_TRANSFER_TYPE_BULK’?
Introduce an alias using the preprocessor to make available the new
define when building against the older version of libusb headers.
