cephadm: remove container_engine argument from test helper function

The with_cephadm_ctx test helper function had an argument that *called*
mock_podman function, thus calling the function at import-time. This can
lead to confusing and unexpected side effects. Because the
container_engine argument is not used by any callers of with_cephadm_ctx
we remove the argument.
All other callers of with_cephadm_ctx that make use of container engine
are already setting `ctx.container_engine = <xyz>` so removing the
argument makes it harder to make the same mistake again in the future.
