[jdk8u-dev] RFR: 8336451: [11u] GHA macos-13 and macos-15 builders are unable to resolve local hostname

Another GHA work-around. Sometimes GHA tests on MacOSX fails with something like:

VM initialization failed for: /Users/runner/jdk-macos-x64/jdk-1.8.0-internal+0_osx-x64_bin/j2sdk-image/jre/bin/java -classpath /Users/runner/work/jdk8u-dev/jdk8u-dev/test-results/testoutput/jdk_tier1/JTwork/classes/com/sun/jdi -Xdebug -Xrunjdwp:transport=dt_socket,address=sjc20-cw752-2deed029-f22c-4b58-be22-6c2b8db93551-8E6FDEE10350.local:49673,suspend=y AccessSpecifierTarg

For test:

com/sun/jdi/RedefineCrossEvent.java

See for example here:

The reason is similar to the failures we saw in JDK 11u. Therefore, I propose to backport the GHA work-around to JDK 8u as well. This should stabilize testing.

Test run with this is here:
