RFR: 8230454: [Graal] Add "com/sun/crypto/provider/KeyFactory/TestProviderLeak.java" to Graal problem list.

[Xiaohong Gong (Arm Technology China)]

Hi,

  Please help to review this small patch:
  Webrev: http://cr.openjdk.java.net/~xgong/rfr/8230454/webrev.00/
  JBS: https://bugs.openjdk.java.net/browse/JDK-8230454
  Jtreg test  "com/sun/crypto/provider/KeyFactory/TestProviderLeak.java" unstably fails with graal
by throwing the OOME during JVMCI compiler initialization.
  It is caused by setting "-Xmx20m" for the application, which makes the java heap not enough for
the VM. A simple fix is to add it to the graal problem list. Hope it's ok for libgraal, so that we can
move it out from the list once libgraal is enabled.

Thanks,
Xiaohong Gong
