fix(bazel-bot): add pipefail option for better logging (#4119)
fix(bazel-bot): add pipefail option for better logging (#4119)

fixes #3134

It's not a complete fix, but at least the bug is out of the current
mysterious state. I'd close #3134 and open a new one when we see the
same failure, with a better logging output.
