[go] Disable TestTracebackAll on Fuchsia

This test has flaked since pprof support was implemented and we're no
closer to fixing it than we were ~4 years ago. Netstack2 isn't being
actively developed and pprof isn't necessary for current work. We're
unlikely to need to fix this, so we'll go back to skipping this test for
now.
