* lisp/emacs-lisp/syntax.el: Use syntax-ppss-table for syntax-propertize.

`syntax-ppss` uses `syntax-ppss-table` while parsing the buffer as well
as when it calls `syntax-propertize`, but `syntax-propertize` can also
be called directly rather than via `syntax-ppss` so it needs to explicitly
use `syntax-ppss-table` as well in order to avoid using sometimes one
table and sometimes another.

(syntax-ppss-table): Move before new use.
(syntax-propertize): Use it.
