Both Mac signing tests failed in latest jdk-jdk repository. Most likely recent regression.

To reproduce run following command:
jtreg -w build/jtreg/work -r build/jtreg/report -jdk build/macosx-x64/images/jdk open/test/jdk/tools/jpackage/macosx/Signing*Test.java

./output/SigningAppImageTest.app: unsealed contents present in the bundle root
