symbol-function: don't break existing compiled code.

When a symbol-function form is used as a syntactic place,
the generated code makes a run-time call to
sys:get-fun-getter-setter. A recent commit changed the
interface of this function, which means that such code
which has been previously comipled (or somehow retained
in macro-expanded form) will break.

* share/txr/stdlib/place.tl (sys:get-fun-setter-getter):
Change the interface so it's backward compatible with the old
one: the first argument is the symbol, like before, and
thanks to optional arguments, it can be called with just that
argument.
(defplace symbol-function): Generate code to call
sys:get-fun-setter-getter accordingly.
