    Description

      JDK-8278549 `UNIX sun/font coding misses SUSE distro detection on recent distro SUSE 15`
      adds SuSE detection by checking SLES os name property in /etc/os-release file.

      opensuse/leap:15.4 docker defines os name property as "openSUSE Leap" in /etc/os-release file which is not recognized as SuSE.

      The issue is reproduced with Oracle jdk-19.0.2 with custom fontconfig.SuSE.properties file copied to jdk-19.0.2/lib directory.


      Steps to reproduce.

      - Download Oracle jdk-19.0.2
      - Copy the attached custom fontconfig.SuSE.properties file to jdk-19.0.2/lib directory.
      - Run the opensuse/leap:15.4 docker and install freetype and dejavu fonts (do not install fontconfig)
      ```
      docker run --rm --security-opt seccomp=unconfined -it opensuse/leap:15.4 bash
      zypper install -y dejavu-fonts
      zypper install -y freetype2
      ```
      - Run HelloImage java sample in the docker
      ```
      import javax.imageio.ImageIO;
      import java.awt.*;
      import java.awt.image.BufferedImage;
      import java.io.File;

      public class HelloImage {

          public static void main(String[] args) throws Exception {

              BufferedImage buff = new BufferedImage(300, 200, BufferedImage.TYPE_INT_RGB);
              Graphics2D g = buff.createGraphics();
              g.setColor(Color.WHITE);
              g.fillRect(0, 0, buff.getWidth(), buff.getHeight());

              g.setColor(Color.BLUE);
              g.setFont(g.getFont().deriveFont(32f));
              g.drawString("Hello, Image!", 50, 50);
              g.dispose();

              File file = new File("hello-image.png");
              ImageIO.write(buff, "png", file);
          }
      }
      ```
      ```
      ./jdk-19.0.2/bin/javac HelloImage.java
      ./jdk-19.0.2/bin/java HelloImage
