Subject: [PATCH] Avoid ANYARGS deprecation warning on modern Rubies

Rather than using rb_define_global_function, use
rb_define_module_function to define the RE2 method on Kernel, avoiding a
deprecation warning from
https://github.com/ruby/ruby/blob/ec37636ab36af36155faa4dbcfebaa161dcf394d/include/ruby/backward/cxxanyargs.hpp.
