Add FileDescriptor Versions of applyTransportModeTransform()

Because there is no way using the Java sockets API to actually
get a socket of AF_INET on mode machines, it is necessary to
provide a way to apply transforms to sockets made using the
native wrapper API, which uses POSIX APIs and will create a
socket that is AF_INET.
