[ruby/reline] Fix failed test

For ruby/ruby repository's AppVeyor CI (Windows environment), `Reline::IOGate.encoding` will be changed from `UTF-8` to `Windows-31J` after the test is run.
So, when `test/reline/test_key_actor_emacs.rb` is loaded, `Reline::IOGate.encoding == Encoding::UTF_8` will be `true`,
but at the time of test execution, `Reline::IOGate.encoding` is `Windows-31J`.
For this reason, I changed the test method to check `Reline::IOGate.encoding` in the test method.
