Fix containerized SwiftRawDisks usage

This patch partitions the defined devices and mounts them on the
hostnode.

It also disables the mount_check inside Swift because it is currently
not possible to detect wether a given directory is a mounted device or
not. This is just a workaround until a better solution has been
implemented in Swift itself.
