Revert^2 "[attestation] Validate client VM's Microdroid kernel in service VM"
This reverts commit bd51176b023dd2069cb7225c5edfd6910d0d709b.
Reason for revert: Reland the change aosp/2855677 and adapt the python
script in environments where Microdroid is not supported such as x86.
PS1 is the same as the original code. There's no change for the
supportive environments x86_64 and arm64.
