test: fix autotest handling of skipped tests

- When running the default configuration of autotest of the make test
  it'd take 900 seconds (15 minutes) for the script TIMEOUT and marks
  Failed for a specific device test that is not supported on the
  system under test.
- Adding the checking for those tests, print out as "Skipped [Not Run]"
  quickly return and continue for next test
