Integrated: 8314672: ProblemList runtime/cds/appcds/customLoader/HelloCustom_JFR.java on linux-all and windows-x64

[Daniel D. Daugherty]

A trivial fix to ProblemList runtime/cds/appcds/customLoader/HelloCustom_JFR.java on linux-all and windows-x64.

This test was previously ProblemListed on linux-all with ZGC via: 

[JDK-8314533](https://bugs.openjdk.org/browse/JDK-8314533) ProblemList runtime/cds/appcds/customLoader/HelloCustom_JFR.java on linux-all with ZGC 

but we have had 7 new failures in different configs since then 
so the ProblemListing needs to be wider. I thought above using 
generic-all, but we haven't seen an macosx-x64 failure since 
mid-May 2020 and have yet to see a macosx-aarch64 failure.
