CC Mode: Stop /**/ spuriously fontifying as a doc comment under gtkdoc

Also fix infinite loops by correcting two regexps.

* lisp/progmodes/cc-langs.el (c-last-c-comment-end-on-line-re)
(c-last-open-c-comment-start-on-line-re): Correct the regexp fragments
"\\*+[^/]" to "\\*+\\([^*/]\\|$\\)".

* lisp/progmodes/cc-fonts.el (gtkdoc-font-lock-keywords): Disallow /**/ for
doc comment fontification.
