[roll] Roll fuchsia Revert "[ffx] Test that the daemon and emulators are cleaned up."

This reverts commit ee04f17d85f7876c69ff5207df3b24342981de04.

Reason for revert: broke ffx-e2e-with-target test on ffx builders because it kills daemon spun up by infra: https://chromium-swarm.appspot.com/task?id=62bb7860fb4e4910

Original change's description:
> [ffx] Test that the daemon and emulators are cleaned up.
>
> ffx isolates are normally torn down by Drop implementations in
> test code that cleans up temporary directories and *should*
> result in the daemon terminating. It seems that we don't already
> have tests which check that the daemon actually goes away, so
> this change adds one.
>
> Having this test was motivated by ffx_e2e_emu which might make
> it more likely for plugin developers to spawn isolates and emulators
> within them. When their tests fail, we want to be sure that there
> aren't "zombie" ffx daemons that hang around. Ideally this test would
> check this by having `ffx daemon self-test drop-isolate` actually
> panic, but that's not yet possible because the subtool is compiled
> with panic=abort (unlike most host test code) and never runs Drop
> impls when panicking. For now the test just drops the isolate and
> returns, allowing its caller to verify that the daemon has exited.
