Yukihiro "Matz" Matsumoto 3fc7dd1858 mruby-proc-ext: Proc#curry should check max arity for lambdas ...

`lambda {|a, b=nil|}.curry(3)` used to silently return a curried Proc;
CRuby raises `ArgumentError` because the lambda accepts at most 2 args.
Use `self.parameters` to compute the upper bound (count `:req`/`:opt`
entries, unbounded if `:rest`/`:keyrest` is present) and add the
corresponding range check alongside the existing minimum check.
