Restructure the hash driver content

Browse Source 
Apply the right define guards for the right purpose. The 'core' hash
driver is included if any hash algorithm is either to be tested through
the test driver, or if it is requested by a user and not accelerated
(i.e. 'fallback'/'software' driver requested for the algorithm).
