(PA-2126) Fix typo in ruby version string

Prior to this commit, running any `puppet foo` subcommand on s390x would fail with

`/opt/puppetlabs/puppet/lib/ruby/2.4.0/s390x-linux/rbconfig.rb:7:in <module:RbConfig>:
  ruby lib version (2.4.4) doesn't match executable version (2.4.4) (RuntimeError)`

This fixes the one-character typo and makes the version string match.
