Adding --add-opens=... flag during AOT cache creation implicitly disables AOT ClassLinking.

Steps to reproduce:
> $WS/build/linux-x64/images/jdk/bin/java -XX:AOTMode=record -XX:AOTConfiguration=test.aotconf -version

F="--add-opens java.base/java.io=ALL-UNNAMED"
$WS/build/linux-x64/images/jdk/bin/java $F -XX:+AOTClassLinking -XX:AOTMode=create -XX:AOTConfiguration=test.aotconf -XX:AOTCache=test.aotcache -Xlog:cds,class+path=info:file=test.aotlog

> grep aot-link test.aotlog
