As part of #1358 : current kata-runtime paths are hard-coded within the root directory. These need to be configurable to point to a rootless location. The default location will /run/usr/$UID, which is constructed by the github.com/containers/libpod/pkg/rootless GetRootlessRuntimeDir function call.

The following changes need to be made:

• Makefile LOCALSTATEDIR
• ctrsMapTreePath from katautils/oci.go
• kataAgent kataHostSharedDir, kataGuestSharedDir, and kataGuestSandboxDir
• storage directory locations
• configuration.toml files: hypervisor kernel and image paths

As of right now, thinking of keeping the configuration.toml and Makefile defaults as is, and leaving it up to the user to modify those depending on if they are running rootlessly or not.
