fix: kf6-kio builds — stubbed HostInfo::lookupHost linker error

- hostinfo.cpp not in cmake KIOCORE source list; workerinterface.cpp
  called KIO::HostInfo::lookupHost which had no implementation
- Replaced HostInfo::lookupHost call with direct QHostInfo::fromName
  in workerinterface.cpp via recipe sed, removed hostinfo.h include
- kf6-kio now publishes 2.4MB pkgar to repo
- Enabled in config. Unblocks kde-cli-tools (kde-cli has its own
  separate build error)
- Blocked count: 12 → 11 (kf6-kio now builds)
