quadlet: Switch log-driver to passthrough

This is much better for the systemd case becase we pass the journal
socket fds directly to the container. This means less copying of the
logs, but it also means the journal will correctly get the peer
process id when it tries to extract things like the name of what
is logging something.

With this we correctly name the logging process rather than claim
everything comes from conmon.
