Mark b425314 Incompatible (dotnet/coreclr#10431)
b425314 has internal logic to determine if it making forward progress
If test takes too long, test self check fails and test aborts with a
failure. This makes this test difficult in GCStress/HeapVerify situations
where run time is substantially longer.
This test was already marked incompatible for x86. Remove x86 condition
to mark incompatible on al platforms.
