Fix circular deps between util-linux and eudev/systemd:

- build util-linux in chapter 5 for both books
- move eudev before util-linux in chapter 6
- make utils-linux libs and headers accessible to /usr in
  "Creating essential ..."
- not related, but forgotten at previous commit: make also libfl flex
  library accessible to /usr
