Test Android and Linux targets as well in addition to LocalLinux target.
In order to keep basic verification easy, list complete list of test
targets in tests/target_configs.yaml.example and keep the default
configuration file for targets simple.
Also:
- Create a test folder on target's working directory.
- Remove all devlib artefacts after execution of the test.
- Add logs to show progress of operations.
