[polly] [Polly][Test] Fix missing -plugin-arg (PR #228221)

[Michael Kruse via llvm-commits]

https://github.com/Meinersbur created https://github.com/llvm/llvm-project/pull/228221

After #226773, plugin options must be passed via -plugin-arg. Fix the regression test from #227311 to the changed command line.
