systemd-serialgetty: Disable the carrier detect requirement for serial consoles

This aligns the params of getty with the ones used in Debian. From the
getty(8) manpage:

,----[ getty(8) manpage ]
|  -L, --local-line
|
|    Force the line to be a local line with no need for carrier
|    detect. This can be useful when you have a locally attached
|    terminal where the serial line does not set the carrier detect
|    signal.
