[lworld] RFR: 8293609: [lworld] Update vmTestbase/nsk/jdi/Accessible/modifiers001 to allow ACC_IDENTITY

[Roger Riggs]

With identity classes Class.getModifiers() can return 0x20 as ACC_IDENTITY.
Previously it never returned the 0x20 bit (was ACC_SUPER).

test/hotspot/jtreg/vmTestbase/nsk/jdi/Accessible/modifier/modifiers001.java should not be clearing 0x20.
