babel: no longer automatically inserting '='s around inline code results

* contrib/babel/lisp/org-babel-exp.el (org-babel-exp-results):
  removing forced verbatim '=' tags from around inline source code
  results, if users want their results displayed in this way they can
  add the '='s easily themselves, but there is no way to remove '='s
  inserted automatically by Org-babel.
