Subject: tests: provide human-readable integration test summary when --verbose

Integration tests will now provide a brief summary for test failures
listed by platform and distribution. The failure summary will only consist
of failed test name and assert error message.

Drop the verbose dictionary of all integration test output because this
content is unreadable given the large number of integration test results
listed within this dictionary.
