util, passt: Close daemon-lifetime fds on exit to avoid Coverity warningHEAD2026_06_11.a9c61ffmaster

conf_open_files() opens three file descriptors (fd_tap_listen,
fd_repair_listen, fd_control_listen) that are held for the entire
daemon lifetime.  Because no close() call exists for them
anywhere, Coverity flags each as INCOMPLETE_DEALLOCATOR. This is
clearly a false positive, but we still want to get rid of this
warning.

We now register the execution context in global area so that
passt_exit() can use it to close these descriptors before calling
_exit().  All exit paths (signal handler, die(), die_perror())
funnel through passt_exit(), so this covers all cases.
