socket-uart: Change to correct systemd type and revise socat pty parameters 

Systemd service file Type "forking" leads to service restart which
caused socket disconnection. ExecStart process was never forked.
Now Type=simple fixed this issue. It' anyway recommended for
long running tasks.

Socat:
- Fixed typo rawer to raw
- Set echo off
- Defined bitrate
