Add systemd startup files to Debian packages

- Create systemd service files for wssshd and wssshc
- Add conditions to prevent conflicts with sysv init
- Update debian/rules to install systemd services
- Update postinst scripts to enable systemd services
- Ensure sysv init has precedence over systemd
