fix: set ok=False when TestAbortAll is raised in run_suite_class

[devimano2011]

Related to #950 and #960

Problem

In run_suite_class() in suite_runner.py, when signals.TestAbortAll is raised, the except block only has pass and does not set ok = False. This means if a test aborts before any failures, the suite exits with code 0 instead of 1.

This is the same issue that was fixed in test_runner.py by PR #997 for issue #960, but run_suite_class() in suite_runner.py was missed.

Fix

Change pass to ok = False in the except signals.TestAbortAll block so that aborting a test suite always results in a non-zero exit code.

In our usage, abort is usually intentional, so we don't necessarily consider this "not ok".
Most common case is, a device doesn't support the feature a test is meant to test, hence abort.

So I'm not sure whether this should be considered "not ok".

[devimano2011]

Thank you for the feedback! That's a valid point — I wasn't aware that abort is often intentional in your usage (e.g. device doesn't support the feature under test).

Looking at PR #997 more carefully, that fix was motivated by cases where TestAbortAll is raised due to an unexpected failure, where exiting with code 0 would silently hide the problem from CI.

Given your clarification, I see a few options:

1. Revert this PR — keep pass in run_suite_class since aborting is considered intentional there.
2. 2. Make it configurable — distinguish intentional aborts (feature not supported) from unexpected ones.
3. 3. Keep the fix — if consistency with test_runner.py is preferred regardless.
      I'll defer to your judgment. Happy to close/revert if this doesn't align with the intended behavior.
