socket-uart: provide uart, kline and lin serial interfaces from one recipe
Start systemd services for providing serial interfaces of remote machine: - UART (ttyUM0) - KLINE (ttyUM1) - LIN (ttyUM2) Caution: UserModule connection settings are hardcoded within the services! BugzID: 56441 Signed-off-by: Ramon Moesching <ramon.moesching@netmodule.com>
