Remove Gnus group name decoding in Gnus agent

No longer necessary, as group names are already decoded.

* lisp/gnus/gnus-agent.el: Remove variable
  gnus-agent-decoded-group-names and function
  gnus-agent-decoded-group-name.
  (gnus-agent-read-group):
  (gnus-agent-group-path):
  (gnus-agent-group-pathname):
  (gnus-agent-fetch-articles):
  (gnus-agent-fetch-headers):
  (gnus-agent-expire-group-1):
  (gnus-agent-regenerate-group): Remove calls in these functions.
