Fix test cases for TOTP
...
RFC 6238 isn't clear enough in the Test Vectors section, and the
different HMAC algorithms use different secrets.

Change totp to take a uint64_t instead of time_t
...
Let the application deal with converting time_t to uint64_t. For TOTP,
it's just a counter.
While there, rename 'granularity' to 'step', as it's used in RFC 6238.
