Add (guix describe) and use it to initialize '%package-search-path'.
* guix/describe.scm: New file. * Makefile.am (MODULES): Add it. * gnu/packages.scm (%default-package-module-path): New variable. (%package-module-path): Honor 'package-path-entries'. * build-aux/update-NEWS.scm (main): Use %DEFAULT-PACKAGE-MODULE-PATH instead of (last (%package-module-path)).
