RFR: 8267056: tools/jpackage/share/RuntimePackageTest.java fails with NoSuchFileException [v2]

[Alexander Matveev]

> For debug build on macOS, runtime which used for test fill be located in /path/jdk-17/fastdebug and /path/jdk-17 will not contain any other files except fastdebug and in this case our check to decide if we need to copy app or runtime will return /path/jdk-17 which is not correct. Fixed by skipping this check for runtime and only using it for app. Also, added ignoring .DS_Store to test which is needed if user used Finder to look inside runtime folder which will cause .DS_Store to be created and will cause test to fail, since this file is not being packaged.
