Java: update regression-test expectations for path-injection[read]

The sink-model generator and the experimental java/file-path-injection
query now observe the new path-injection[read] sub-kind for the
FileInputStream and Files.copy source-argument models.

- CWE-073 FilePathInjection.expected: refresh the models table for the
  renamed kind on FileInputStream(File); alerts unchanged.
- modelgenerator Sinks.java: update the inline sink annotation for
  copyFileToDirectory(Path,Path,CopyOption[]) Argument[0] to the new
  path-injection[read] sub-kind, mirroring the library change.
