tpm/tests: Ignore test_root_key_check case

Current situation:

 1. The test depends on a TPM being available in the system.
 2. The connection settings to the TPM have to be changed to be
    in line with the TPM available in the system.
    Currently, the hardcoded settings are set to test with the
    software TPM enabled by the CI.

Therefore:

 * Ignore the test by default. Each developer can run their tests
   according to the TPM configuration if it's needed.
 * Explicitly run the test in CI to make sure this is tested at
   least with the software TPM.
