runtime: skip TestSegv failures with "morestack on g0" on darwin/amd64

This failure mode has been present since at least 2020-06-08. We have
enough information to diagnose it, and further failures don't seem to
be adding any new information at this point: they can only add noise,
both on the Go project's builders and in users' own modules (for
example, when run as part of 'go test all').

For #39457
