[age restriction] progress 18/n - attestation tested

- Unit-tests for commit, derive, attest and verify added, with multiple
  combinations of minimum age and commited age.
- Fixed crypto implementation (eddsa -> ecdsa)
- Using now standard functionality from GNUNET:
  GNUNET_CRYPTO_ecdsa_{private,public}_key_derive

All tests pass (unit tests in util/ and 'make check' in testing).
