When one of the asn1_time_compare_test fails, it is difficult to
determine which test failed.

For example, currently it just outputs:

```
$ ./tests/asn1time 
  ... (snip)...
ASN1_TIME_compare tests...
140524144512Z vs. 150923032700Z: want -1, got 0
Time overflow tests...
```

Therefore, this patch adds some logs to make debugging easier.
