[CI] Fix conditional for RUBYOPT
Since GitHub has no real ternary [operator], the second expression
must be "truthy" value instead of an empty string which is evaluated
as `0`.

- Some bundler tests seem trying to install old Rack where
  `Rack::Utils.byte_ranges` method has been deprecated once.

- Racc tests do not seem aware about warnings very well.
