[PATCH 2/2] test/py: efi_secboot: adjust secure boot tests to code changes

[Ilias Apalodimas]

The previous patch is changing U-Boot's behavior wrt certificate based
binary authentication.  Specifically an image who's digest of a
certificate is found in dbx is now rejected.  Fix the test accordingly
and add another one testing signatures in reverse order

changes since RFC:
- Added another test cases checking signature hashes in reverse order
