bug#13614: [24.3.50] `font-lock-syntactic-keywords' is used in cperl-mode

[Stefan Monnier]

> In L1869 of lisp/progmodes/cperl-mode.el in trunk r111664:
>       (setq font-lock-syntactic-keywords
>               ...

> But `font-lock-syntactic-keywords' is an obsolete variable,
>  `syntax-propertize-function' is recommended.

I installed the patch below (into trunk) to silence it.
