net-dns/dnscrypt-proxy: version bump to 1.6.0 and various fixes

* remove unused eutils inherit
* fix dependency on sys-apps/systemd (it's not just RDEPEND)
* add missing DEPEND on virtual/pkgconfig
* remove automagic dependency on ldns to avoid dependency
  breakage and depend on it unconditionally (there is no
  build-system switch)
* don't install COPYING, it's already in LICENSE variable,
  also simplify DOCS string
* add pkg_postinst() information on usage
* minor cosmetic changes
