E2E: add kind VolumeSnapshotClass test data (#10236)

BeforeSuite applies testdata/volume-snapshot-class/<provider>.yaml when
CSI is enabled, and there is no kind.yaml, so the suite fails before any
spec runs and none of the existing CSI tests can run on kind.

This adds a class for csi-driver-host-path. The driver ships its own, but
it lacks the velero.io/csi-volumesnapshot-class label so Velero never
selects it. Nothing sets FEATURES=EnableCSI for kind yet, so no test that
runs today is affected.
