Use RTC_DISALLOW_COPY_AND_ASSIGN in webrtc/base/sigslottester.h

Use RTC_DISALLOW_COPY_AND_ASSIGN in webrtc/base/sigslottester.h

It was incorrectly using a older version of the macro, which
wasn't discovered since the code wasn't built in WebRTC until now.

I moved webrtc/base/sigslottester.h from rtc_unittests into
rtc_base_test_utils instead to make it more usable.
