Tracing: add explicit dtor to TracingMuxerFake

Some SDK users hit linking errors when building perfetto.cc
The cause is uknown (esepcially given they were building the
same perfetto.cc in 3 targets with the same compiler and only
one failed).

The linking error was:
'perfetto::internal::TracingMuxerFake::~TracingMuxerFake()'
buck-out/gen/arvr/third-party/perfetto/perfetto_sdk#android-arm64,static/libperfetto_sdk.a(out.o):perfetto.cc:vtable for perfetto::internal::TracingMuxerFake: error: undefined reference to 'perfetto::internal::TracingMuxerFake::~TracingMuxerFake()'
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
