Test: Bugtool dump in a folder, not in tar format.
Test: Bugtool dump in a folder, not in tar format.

Bugtool provides a lot of information, and for each test we have two new
tar files that have a weird name when debugging. With this change the
bugtool information will be in a separate folder and will make debugging
faster.

Example:
```
breo.acalustra.com ➜  test git:(ReporBugtool) ✗ ls test_results/110-/K8sValidatedServicesTest_MyFail -1 | grep bugto
bugtool-cilium-cwfmx
bugtool-cilium-rk89p
```
