RFR: 8231296: ZGC: vmTestbase/nsk/jvmti/Allocate/alloc001/ fails

Hi Igor,

I don't think it belongs in the problem list, for two reasons:

1) The test doesn't fail because of a bug. It fails because ZGC doesn't 
currently support that use case. In other words, the test shouldn't be 
testing something that isn't supposed to work.

2) As far as I know, the test in question is part of rt-tiers, where 
it's executed with the default GC (G1). So, the problem is typically 
only visible when doing non-CI testing with ZGC enabled.
