Switch to ForkWithFlags for InitProcess (it will not reset coverage).
Explicitly dump coverage after initial namespace setup.
Return instead of exiting from libunwind sandbox.

This removes dependency on unwind from forkserver,
which should reduce binary size for all the custom forkservers (also the SAPI generated ones).
Unwind was only ever used by the global forkserver anyhow

This makes should ensure global forkserver will be single threaded before forking the sandboxees as it does not go through WaitAndFork.
Waiting for sanitizers is not needed in the monitor and should reduce latency
by 1 second for all sanitizer builds. Currently it'll always wait up to 1 seconds for the process to become single-threaded, which will never happen as monitor itself is running in a separate thread.

This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.
Follow-up changes will move `sandbox2/util.h` and rename the remaining
`sandbox2/util` folder.
