Fix machine log dump

Fix machine log dump regression intorduced by !2531 (merged)

First dump works properly, but subsequent runs are failing with:

The Service "machine-dump" is invalid: spec.ports[1].name: Duplicate value: "dump"

Like here for example: https://gitlab.com/sylva-projects/sylva-core/-/jobs/7221246389

Force is now required as port service port is patched, and kubectl use it as a merge key when it attempts to recreate the service.
