Revert of Enabling 'gn check' on //webrtc/test.

Revert of Enabling 'gn check' on //webrtc/test. (patchset #3 id:90001 of https://codereview.webrtc.org/2815103005/ )

Reason for revert:
Breaks Chromium because in Chromium we import WebRTC with rtc_include_tests=false (https://bugs.chromium.org/p/chromium/issues/detail?id=713179#c6).

This also reverts the webrtc/test/fuzzers/BUILD.gn introduced in
https://codereview.webrtc.org/2717083002. We want to try to avoid to revert
the whole CL that enables 'gn check' on webrtc/base.
