nixos/hydra: remove hydra-migration upgrade path

This should NOT be backported to 20.09!

When 21.03 is released, the DB changes are about a year old and
operators had two release cycles for the upgrade. At this point it
should be fair to remove the compat layer to reduce the complexity of
the module itself.
