tools: libxl: Refix "Initialise the fd of the unused half of a datacopier"

Applying the series out of order led to d72befc35f31 "tools/libxl:
Identify copywhat in stream v2 datacopiers" unintentionally reverting
part of 21d9b079e538 "tools/libxl: Initialise the fd of the unused
half of a datacopier".

Put this back.
