testimage: retrieve ptests directory when ptests fail

TESTIMAGE_FAILED_QA_ARTIFACTS is set with a default, minimal list of files
to retrieve whenever a runtime test fails.
Add ptests directory to the list so we can get ptests artifacts (eg: logs)
whenever a ptest fails. By appending the ptest directory with the
multiconfig component in the path, only failing ptests will lead to
corresponding ptest artifacts retrieval, instead of all ptests artifacts
retrieval. While doing this addition, reinforce default value using "="
operator to make sure to get the default list in any case.
