* Remove duplicate definitions of storage-related flags for kpod, since
we set them in helpers.bash now, and the other locations that were
also setting it were doing so after loading the definitions in
helpers.
* Set kpod storage flags after checking if we need to force use of the
"vfs" storage driver for cri-o, to make sure kpod also ends up with
the same override if we're using one.
