Fix the wrong usage of PassFailJFrame.forcePass() in some manual tests from java.awt.Desktop package. These tests should be fixed similar to JDK-8352109 and jtreg.SkippedException should be used instead of PassFailJFrame.forcePass().
Affected tests:
1. https://github.com/openjdk/jdk/blob/master/test/jdk/java/awt/Desktop/BrowseTest.java
2. https://github.com/openjdk/jdk/blob/master/test/jdk/java/awt/Desktop/OpenTest.java
3. https://github.com/openjdk/jdk/blob/master/test/jdk/java/awt/Desktop/EditAndPrintTest/EditAndPrintTest.java
