8244284: Two tests in test/hotspot/jtreg/vmTestbase fail with --illegal-access=deny

[Alan Bateman]

I need a reviewer for an tiny update to two tests in 
test/hotspot/jtreg/vmTestbase/ndk/jdi. Both tests need the non-exported 
package com.sun.tools.jdi to be opened because they instantiate 
ObjectReferenceImpl via its non-public constructor. This change is 
needed in advance of denying illegal access by default.
