Piotr Tabor 04b91945f4 pkg/testutil: Ignore flakes due to "leaked" testing.runTests goroutine.
The flake happened e.g. in:
https://travis-ci.com/github/etcd-io/etcd/jobs/386607570

```
--- PASS: TestWatchClose (0.37s)
PASS
Unexpected goroutines running after all test(s).
1 instances of:
testing.runTests.func1.1(...)
	/usr/local/go/src/testing/testing.go:1289 +0x60
created by testing.runTests.func1
	/usr/local/go/src/testing/testing.go:1289 +0xdb
FAIL	go.etcd.io/etcd/v3/clientv3/integration	344.389s
FAIL
```

This is implementation detail of Go testing.lib and we should not worry.

pkg/ is a collection of utility packages used by etcd without being specific to etcd itself. A package belongs here only if it could possibly be moved out into its own repository in the future.
