Move all storage configuration defaults into libpod

Instead of passing in defaults via WithStorageConfig after
computing them in cmd/podman/libpodruntime, do all defaults in
libpod itself.

This can alleviate ordering issues which caused settings in the
libpod config (most notably, volume path) to be ignored.
