File 1030-systemd-service-earlier.patch of Package opensnitch

Start firewall before network and harden service.

Based on Debian patch by Petter Reinholdtsen:
https://github.com/evilsocket/opensnitch/pull/1019
https://salsa.debian.org/pere/opensnitch

- Start before network-pre.target instead of after network.target
- Protect daemon from OOM killer (OOMScoreAdjust=-1000)
- Use basic.target instead of multi-user.target
