Use formatted source for compile_data_generated test

The unformatted source caused CI failures:
- --config=rustfmt aspect caught the formatting issue during build
- rustfmt_failure_tester.sh couldn't format it due to norustfmt tag

Use a properly formatted source instead. The test still exercises
the code path where compile_data has a generated file (triggering
transform_sources), verifying that rustfmt correctly finds and
checks the sources rather than silently skipping them.
