Revert^2 "Make salt in Microdroid's instance img obsolete"

Salt has been used to provide differentiation of secrets of 2
non-protected VMs (as hidden input in DICE). Have hidden input be
derived from instance_id of the (non protected) VM. In all other cases,
it will be all 0s.

Test: Microdroid tests use this code path.
Bug: 291306122
Re-revert: The reason for failures was a different issue(b/291306122),
this patch is harmless.

Android Virtualization Framework (AVF)

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.

Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.

If you want a quick start, see the getting started guideline and follow the steps there.
