[tsan] Fix warnings in tsan_interceptors.cc from expansion of variadic macros

C99 technically requires the rest arguments to be used in C variadic macros.
This presents a problem with the macro SCOPED_TSAN_INTERCEPTOR when func
takes no arguments. This happens with the function pause. Like other void
argument functions, we pass in a fake argument to avoid this warning.
