gnu: knot: Build separate outputs.

* gnu/packages/dns.scm (knot)[outputs]: New field adding :doc, :lib,
and :tools outputs.
[arguments]: Add #:configure-flags to install into :doc and :lib.
Add a new ‘split-:tools’ phase to install into :tools.
Add a new ‘break-circular-:lib->:out-reference’ phase to do just that.
