signer: syncronize image packing to what we have in build image phase.
This follows steps we have in build image phase to have parity in image
packing.
* Discard reapply selinex context. This looks not needed once
re-signing should not change selinux context. Instead we could do
similar to build image, pass file context to mksquashfs
* Apply mksquashfs params based on image type, container/vm. This
fixes proper block size and image compression algorithm
* Remove old image before packing to prevent mksquashfs merge attempt

BRANCH=none
TEST=locally signed vm (kohaku) and container (hana): arc.Optin*,
arc.Preopt*. Also checked final image size. With this CL it is
reduced to 150Mb(vm) and very close to original image size
(delta is less than 0.1%)
