Subject: [PATCH] init: exit clock_worker child process on failure

If clock_worker() returns due to an error (socket creation, bind, or
recv failure), the child process falls through into the rest of main(),
forking again and duplicating the workload execution.

Add _exit(1) after clock_worker() to prevent the child from continuing.

Fixes: https://github.com/containers/libkrun/issues/580
