Add the following new options, based on net-mgmt/ping_exporter:
+# blackbox_exporter_syslog_output_tag (str): Set syslog tag.
+# Default is "blackbox_exporter". See daemon(8).
+# blackbox_exporter_syslog_output_priority (str): Set syslog priority.
+# Default is "notice". See daemon(8).
+# blackbox_exporter_syslog_output_facility (str): Set syslog facility.
+# Default is "daemon". See daemon(8).
the defaults are unchanged from before, i.e. it outputs at daemon.notice.
