Currently, if journald coredumps, the coredump is written to /var/lib/systemd/coredump but the coredump metadata is not written to the journal meaning we can't find out about the coredump's existence via the journal. This means that coredumpctl can't be used to work with journald coredumps, as well as any other tools that rely on journald to know about coredumps. To solve the issue, let's have systemd-coredump try to write systemd-journald coredump metadata to the journal. We have to be careful though, since if journald coredumps, there's no active reader on the receive end of the journal socket, so we have to make sure we don't deadlock trying to write to the socket. To avoid the deadlock, we put the socket in nonblocking mode before trying to write to it.
