test: Fix a mem leak reported by Coverity

Here is the report:

  *** CID 1531835:  Resource leaks  (RESOURCE_LEAK)
  /src/test/test_crypto_slow.c: 683 in test_crypto_equix()
  677
  678           /* Solve phase: Make sure the test vector matches */
  679           memset(&output, 0xa5, sizeof output);
  680           equix_result result;
  681           result = equix_solve(solve_ctx, challenge_literal,
  682                                challenge_len, &output);
  >>>     CID 1531835:  Resource leaks  (RESOURCE_LEAK)
  >>>     Variable "solve_ctx" going out of scope leaks the storage it points to.
