Change https://golang.org/cl/140121 mentions this issue: go/packages: skip TestLoadImportsC when Go has been built without cgo

gopherbot pushed a commit to golang/tools that referenced this issue Oct 5, 2018
This test is unsurprisingly failing on the nocgo builder because
the cgo packages don't exist on those builders.

Updates golang/go#28040

Ping somebody. Please fix or skip these tests.

Red on the dashboard is distracting.
