The accelerated, instruction based implementations of SHA1, SHA2 and SHA3 are autoloaded based on CPU capabilities, given that the code is modest in size, and widely used, which means that resolving the algo name, loading all compatible modules and picking the one with the highest priority is taken to be suboptimal. However, if these algorithms are requested before this CPU feature based matching and autoloading occurs, these modules are not even considered, and we end up with suboptimal performance. So add the missing module aliases for the various SHA implementations.
