Jdk7Symlink does not delete the test symlink

[arsi-apli]

In org.gradle.internal.nativeintegration.filesystem.jdk7.Jdk7Symlink.doesSystemSupportSymlinks() is an bug. The created test symbollink is not deleted.

} finally {
            try {
                if (sourceFile != null && sourceFile.toFile().exists()) {
                    Files.delete(sourceFile);
                }
                if (linkFile != null && linkFile.toFile().exists()) {
                    Files.delete(linkFile);
                }
            } catch (IOException e) {
                // We don't really need to handle this.
}

The expression linkFile.toFile().exists() is always false.
Please change that to:

if (linkFile != null ) {
      Files.deleteIfExists(linkFile);
 }

Seemed related and small enough to fix it in the context of PR #8138 😉
