optparse: Suppress warnings
Ruby warns "instance variable `@version` not initialized" for optparse when it receives `--version` option.
`test.rb`
```ruby
require 'optparse'
Version = '1'
OptionParser.new.parse(ARGV)
```
```
$ ruby -w test.rb --version
/home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1168: warning: instance variable @version not initialized
/home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1175: warning: instance variable @release not initialized
test 1
```
This change will suppress the warnings.
