Move security opts to HostConfig

These settings need to be in the HostConfig so that they are not
committed to an image and cannot introduce a security issue.

We can safely move this field from the Config to the HostConfig
without any regressions because these settings are consumed at container
created and used to populate fields on the Container struct.  Because of
this, existing settings will be honored for containers already created
on a daemon with custom security settings and prevent values being
consumed via an Image.
