[rubygems/rubygems] Fix extension paths in generated standalone script

The paths for extensions of gems would contain the hardcoded ruby
version on which the extension was built. This will replace it with
runtime ruby version like the parent version directory. It will make the
standalone script compatible between different ruby version installations.
