Fontify the pipe operator in the cc-mode independent php-mode

php-pipe-op and its rule arrived on master (#821) in the CC Mode based
php-mode.el, which this branch renames to php-cc-mode.el; the new mode
body needs the same rule for the same reason.  Without it the
comparison-operator matcher claims the `>' of `|>' and leaves the `|'
plain.
