Subject: [PATCH 2/2] Fix require issue with file extension priority

If `require "a"` is run when two folders have been specified in the -I
option including a "a.rb" file and a "a.so" file respectively, the ruby
spec says that the ".rb" file should always be preferred. However, the
logic we added in https://github.com/rubygems/rubygems/commit/6b81076d9
to make the -I option always beat default gems does not respect this
spec, creating a difference from the original ruby-core's require.

[the ruby spec says]: https://github.com/ruby/spec/blob/d80a6e2b221d4f17a8cadcac75ef950c59cba901/core/kernel/shared/require.rb#L234-L246
