Subject: Remove broken dynamic caching patterns

Avast/Symantec have been completely no-op and useless for years since AV updates for those are streamed to clients hundreds time every day. Suspect same story for Avira. The WU refresh_patterns was broken and don't work reliably anyway. People can define their own patterns if needed without maintenance burden for package maintainers.
