wusb: switch to cbcmac transform
The wusb code takes a very peculiar approach at implementing CBC-MAC, by using plain CBC into a scratch buffer, and taking the output IV as the MAC. We can clean up this code substantially by switching to the cbcmac shash, as exposed by the CCM template. To ensure that the module is loaded on demand, add the cbcmac template name as a module alias.
