ui: Bypass Texinfo parsing and rendering for searches.

This makes search queries such as:

  LANGUAGE=fr guix package -s utilitaire -s recherche

about 6 times faster.

* guix/ui.scm (%package-metrics): Do not use 'package-synopsis-string'
and 'package-description-string' to bypass Texinfo parsing and
rendering.
