Currently, if function was created as C stored procedure or as Lua
persistent function (with body argument) via box.schema.func.create,
all types of router.call and router.map_callrw cannot find it and
return Procedure 'name' is not defined error.
This is cased by the fact that both of these function use local_call,
which invokes net_box.self.call. It didn't work with these type of
functions before Tarantool 3.0.0-beta1-18. Let's use box.func, where
it's needed instead of net_box.self.call in local_call.
