test-runner: add option to write final status to file

Browse Source 
Running the tests inside a VM makes it difficult for the host to figure
out if the test actually failed or succeeded. For a human its easy to
read the results table, but for an automated system parsing this would
be fragile. This adds a new option --result <file> which writes PASS/FAIL
to the provided file once all tests are completed. Any failures results in
'FAIL' being written to the file.
