x86/opcode: Add ERET[US] instructions to the x86 opcode map
ERETU returns from an event handler while making a transition to ring 3,
and ERETS returns from an event handler while staying in ring 0.
Add instruction opcodes used by ERET[US] to the x86 opcode map; opcode
numbers are per FRED spec v5.0.
