[jdk11u-dev] RFR: 8271828: mark hotspot runtime/classFileParserBug tests which ignore external VM flags

[Andrew Lu]

I backport this for parity with 11.0.23-oracle.
test/hotspot/jtreg/runtime/classFileParserBug/ClassFileParserBug.java
test/hotspot/jtreg/runtime/classFileParserBug/TestEmptyBootstrapMethodsAttr.java
Copyright.

test/hotspot/jtreg/runtime/classFileParserBug/TestBadPackageWithInterface.java
this test has not been added to jdk11u-dev, so ignore the backport.
