CAPO: Use KUBEBUILDER_ASSETS_DIR instead of XDG_DATA_HOME

[mdbooth]

KUBEBUILDER_ASSETS_DIR requires backporting
kubernetes-sigs/cluster-api-provider-openstack#1710, which will require a separate patch.

Interacting with pj-rehearse

Comment: /pj-rehearse to run up to 10 rehearsals
Comment: /pj-rehearse skip to opt-out of rehearsals
Comment: /pj-rehearse {test-name}, with each test separated by a space, to run one or more specific rehearsals
Comment: /pj-rehearse more to run up to 20 rehearsals
Comment: /pj-rehearse max to run up to 35 rehearsals
Comment: /pj-rehearse auto-ack to run up to 10 rehearsals, and add the rehearsals-ack label on success
Comment: /pj-rehearse abort to abort all active rehearsals

Once you are satisfied with the results of the rehearsals, comment: /pj-rehearse ack to unblock merge. When the rehearsals-ack label is present on your PR, merge will no longer be blocked by rehearsals.
If you would like the rehearsals-ack label removed, comment: /pj-rehearse reject to re-block merging.

Whatever this does, the tests are currently broken anyway, and the repo is still not in the OCP payload. Thanks and good luck 👍
