Few configuration and zone files were moved into tarball by commit
55b04de09a. It makes tracking of changes difficult, hardens rebases,
makes difficult building without proper lookaside cache. Those files are
tiny, no need to hold them inside compressed binary archive. Move them
out.
Replaces also few places with proper directory macros.
- removed caching-nameserver subpackage and move configfiles from there
into main bind package as default configuration
- major changes in default configuration
