I wasn't sure about this. I copied it from another package but
technically there is no reason for this to be dependent on systemd.
There's nothing about _building_ this package that cares if systemd
has been built. All the systemd related options do is make it install
the syslog-ng.service file.

There's a bug here. Every time this is built a new configuration line
is inserted.

Because syslog-ng is so configurable the default configuration shipped
tries to show off some of the features. I'm actually wondering if a
simplified "buildroot" syslog-ng.conf would be better. It would also
eliminate the need for the SYSLOG_NG_REMOVE_JSONFORMAT hook.
