Patrick Ohly 02ce619078 e2e log: fix full stacktrace with Ginkgo 1.10.0
Ginkgo 1.10.0 includes the relevant fix for dumping the full stack
(https://github.com/onsi/ginkgo/pull/590), so when using that release
we can simplify the logging unit test.

By changing the skipping, we can avoid the rather volatile util.go
entries. However, that gomega is part of the stack trace still needs
to be fixed in Gingko.
