Revert "main-loop.c: Handle SIGINT, SIGHUP and SIGTERM synchronously"
This reverts commit 15124e142034d21341ec9f1a304a1dc5a6c25681. It breaks
debuggability of qemu and is no longer needed as the problem has
now been addressed in a different way.
Instead we provide a comment about why these signals must be
handled asynchronously.
