Fix bash condition evaluation in init scripts

- Separate PID file reading from process checking
- Prevent command substitution failures in kill command
- Add proper error handling for PID file operations
- Fix false 'watchdog failed' reports due to bash syntax issues
- Fixed both wssshd and wssshc init scripts
