Fix watchdog daemonization issue

- Watchdog now properly daemonizes by running main() in background
- Removed complex PID file waiting logic that was causing issues
- Simplified start case to just run main() and check for PID file
- Fixed both wssshd and wssshc watchdogs
- Watchdog processes should now persist after script exits
