Yukihiro "Matz" Matsumoto 9d8d41006b mruby-regexp: alias original String#split before overriding it ...

`class String; def split` in mruby-regexp/mrblib/string_regexp.rb
replaced the C-defined String#split rather than overriding it, so
the in-Ruby `return super if pattern.nil?` paths raised
NoMethodError for any `"x".split(...)` call once mruby-regexp was
loaded (the default full-core production binary).

The regression wasn't caught by the test suite because per-gem
tests run under mrb_open_core() with only the gem's dep_list, so
the broken override is never visible from test/t/string.rb
(mruby-test, not mruby-regexp).

Add `alias __split split` at the top of the override class body,
which captures the C-defined method, and change the Ruby override
to delegate via `__split(pattern, limit)` for non-regexp fallback
paths. Add a bintest under mruby-bin-mruby that runs through
bin/mruby (full gem load) to catch this regression class.
