DataPipeTest.SendConsumerAndCloseProducer flakily times-out under Fuchsia/x64/Debug FYI bot

Project Member Reported by w...@chromium.org, Apr 10 2018 
In https://ci.chromium.org/buildbot/chromium.fyi/Fuchsia%20(dbg)/18123 this failed with:

In successful runs this test takes ~9.4s:

[00076.740] 04033.04094> [284/1016] DataPipeTest.SendConsumerAndCloseProducer (9412 ms)

RunTestClientAndGetExitCode() uses action_timeout(), which defaults to 10s - so this test is always perilously close to flaking, even when it passes.

Will disable this test in Debug, pending a fix for the process-launch performance issues for Debug/component binaries.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/9ea3e3cf0148a0685ebf8f7af4979e31735d94e5

commit 9ea3e3cf0148a0685ebf8f7af4979e31735d94e5
Author: Wez <wez@chromium.org>
Date: Tue Apr 10 22:29:58 2018

Disable or filter some more tests which often flake under Fuchsia.

- Disable ProcessUtilTest.LaunchWithHandleTransfer under Debug builds,
  since launching the child process is currently too time consuming.
- Modifies that test to distinguish the child process failing to send
  data from the timeout case.
- Disable SecurityTest.NewOverflow, which fails under Fuchsia/Debug
  builds due to the SDK exporting the wrong new[].
- Disable RTCRtpSenderTest.GetStats, which is part of a suite of tests
  which appear to be inherently flaky, but fail most often under Fuchsia.
- Filter DataPipeTest.SendConsumerAndCloseProducer
