distro: ktn-base.inc: Disable hash equivalence by default
The poky configuration enables this by default as it can prevent rebuilds for changes that do not affect the output of the task.
This works for local builds, but when using a remote sstate cache it requires to use a hash equivalence server. In Dunfell there is no easy way to set a remote hash equivalence server and we currently don't have one running for the shared sstate cache.
For now let's revert to OEBasicHash which should give us much better reuse quotas as when building against a shared sstate. The positive effect of this will probably/hopefully outweigh the improvements achieved by OEEquivHash.
