test: no longer directly use the sidedata config and requirements

They are on their way out, so we simply use revlogv2 in these cases.

Some test does not requires explicite request for the revlogv2 format since the
upgrade to a side-data-capable format is impled by
`exp-use-copies-side-data-changeset`.
