Adjust parameters passed to kselftest jobs

Currently the set of parameters passed to kselftest suite run in the new system is limited to `job_timeout`, kselftest `collections` and specific `tests` (case name). Following steps should allow extending this set:

1. Make sure that requested parameters are supported in the [`run_kselftest.sh`](https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/tree/tools/testing/selftests/run_kselftest.sh)
2. Add these parameters in the [`kselftest.sh` runner](https://github.com/kernelci/test-definitions/blob/491dd1c8015ae06e22bfb5093a16e34e747a2e48/automated/linux/kselftest/kselftest.sh#L192)
4. Add parameters to the [LAVA test definition template](https://github.com/kernelci/test-definitions/blob/491dd1c8015ae06e22bfb5093a16e34e747a2e48/automated/linux/kselftest/kselftest.yaml#L63)
5. Add parameters to the [LAVA test step template](https://github.com/kernelci/kernelci-core/pull/2417/files#diff-414f5f85bd455fff00c59c1bf9413e06136da37c9635c043fa875efb67e48497R22)
6. Finally set parameters in the [Pipeline configuration](https://github.com/kernelci/kernelci-pipeline/pull/448/files#diff-ee2150cd1504091b3cc4440523177ab60eed7d756009edceb3ba3eb46be1a423R229)

Start by checking the supported parameters in tools/testing/selftests/run_kselftest.sh. Then trace the existing parameter handling through automated/linux/kselftest/kselftest.sh, kselftest.yaml, the LAVA test step template, and the pipeline configuration referenced in the issue. Done means the requested supported parameters are passed through each layer and set in the pipeline.
