Equality between bytes/bytearray and Array[Byte]/List[Byte] no longer works

[slozier]

#567 broke the following interop scenarios:

b = bytes(range(5))
System.Array[System.Byte](b) == b
System.Collections.Generic.List[System.Byte](b) == b
System.Array[System.Byte](b) == bytearray(b)
System.Collections.Generic.List[System.Byte](b) == bytearray(b)

While during initial development this is probably good (to help discover bugs) it might be worth enabling this scenario in the future.
