Add a checker for signature boundary in verifier
The 'signature_start' variable marks the location of the signature
from the end of a zip archive. And a boundary check is missing where
'signature_start' should be within the EOCD comment field. This causes
problems when sideloading a malicious package. Also add a corresponding
test.
Bug: 31914369
Test: Verification fails correctly when sideloading recovery_test.zip on
angler.
