net-analyzer/suricata: bump to 6.0.0

Okay, this has turned out to be easier than I thought it might be.
Note to self: since suricata-6 no longer supports unified2 output and
suricata-5 is still supported upstream (even 4 will only reach end of
life on 2020-12-31), keep the latter around for at least a bit longer.
