Allow the socket directory to be directly configured by the shim manager with reasonable defaults when not set. The default for root users will still be the same directory under the default state directory. For non-root users a temp directory will be used as default if the state directory is not owned by the user. Signed-off-by: Derek McGowan <derek@mcg.dev>
