In this test case, a image binary, helloworld.efi.signed, is willfully
modified to print a corrupted message while the signature itself is
unchanged.
This binary must be rejected under secure boot mode.

The previous patch adds support for rejecting images when the sha384/512
of an x.509 certificate is present in dbx. Update the sandbox selftests

The test case 5 in test_signed (multiple signatures) must be modified
and aligned with the change introduced in the previous commit
("efi_loader: signature: correct a behavior against multiple signatures").

In this test case, an image may have a signature with additional
intermediate certificates. A chain of trust will be followed and all
the certificates in the middle of chain must be verified before loading.

It won't be very useful to customize HELLO_PATH and EFI_SECBOOT_IMAGE_NAME
under the current code base. So just remove them.

Signature database (db or dbx) may have not only certificates that contain
a public key for RSA decryption, but also digests of signed images.
In this test case, if database has an image's digest (EFI_CERT_SHA256_GUID)
and if the value matches to a hash value calculated from image's binary,
authentication should pass in case of db, and fail in case of dbx.

In this test case, an image is signed multiple times with different
keys. If any of signatures contained is not verified, the whole

Revocation database (dbx) may have not only certificates, but also
message digests of certificates with revocation time
(EFI_CERT_X509_SHA256_GUILD).
In this test case, if the database has such a digest and if the value
matches to a certificate that created a given image's signature,
authentication should fail.

Python's autopep8 can automatically correct some of warnings from pylint
and rewrite the code in a pretty print format. So just do it.

A time authenticated variable cannot be overwritten with another value
with the same time stamp. So we must ensure the correct sequence of time
stamps when generating out test data.
Using parameter -t for sign-efi-sig-list gives reproducible results and
avoids sleep statements.

If udisksctl is present
test/py/tests/test_efi_secboot/conftest.py
fails because the disk image is never mounted.
Normal users can only mount fuse file systems. Unfortunately fusefat is
still in an experimental state and seems not to work here correctly.
So as we have to be root or use the sudo command anyway delete all coding
referring to udisksctl.

We should not use mount point /mnt as this directory or one of its
sub-directories might already be in use as active mount points. Instead
create a new directory in the build root as mount point.

Remove debug print statements that have been commented out. print without
parentheses is anyway invalid in Python 3. And pytest anyway filters out
the output if there is no exception reported.

A fixture for UEFI secure boot tests (image authentication and variable
authentication) is defined. A small file system with test data in a single
partition formatted in fat is created.
This test requires efitools v1.5.2 or later. If the system's efitools
is older, you have to build it on your own and define EFITOOLS_PATH.
