Disable a flaky test for SysFs

[pgrawehr]

This report indicates that this particular test is responsible for most of the helix test failures.

Thanks!

Have we found evidence of runs where ONLY this test fails? What I've seen in the past, is that sometimes a board would end up in a bad state of pinmode on the input pin and it essentially fails around 10 or so tests. If that's the case, then I think that this PR isn't really getting us much value, and it is dropping coverage. My suggestion is wait for a PR to fail the tests and validate that this test is the only one failing, sound good?

As I already have noted: This statistic shows that this is the only test that failed in all of the recent builds. I've manually checked 2 or 3 recent helix failures, and it was always this test (and only this test).

I see, sorry @pgrawehr I missed that. One last ask, can we please log an issue to track the fix of the test, and add a comment where you are disabling it to point to that issue? Basically the same thing that @krwq suggested.

Ticket #629 exists already.

The issue could also be related to #1581
