Fix edebug-spec on c-lang-defvar.

This allows c-lang-defvars with the symbol 'dont-doc in the place of the
optional documentation to be instrumented for edebug.

lisp/progmodes/cc-langs.el (top-level): Amend the edebug-spec for
c-lang-defvar.
(c-opt-identifier-concat-key, c-decl-prefix-or-start-re): remove redundant
'dont-doc.
