runtests: show name and keywords for failed tests in summary

Useful to see what the numbers listed in the `TESTFAIL:` and `IGNORED:`
lines mean. Also list test keywords to help catching failure patterns.

Example:
```
FAIL 1034: 'HTTP over proxy with malformatted IDN host name' HTTP, HTTP GET, HTTP proxy, IDN, FAILURE, config file
FAIL 1035: 'HTTP over proxy with too long IDN host name' HTTP, HTTP GET, HTTP proxy, IDN, FAILURE

TESTFAIL: These test cases failed: 1034 1035
```

Closes #14174
