[Classic][arm64/armhf] The options combination causes generate_manifests() function failed

[Soar Huang]

When building classic image, if the target arch is arm64/armhf and with options "-f cloud-image", ie.

---------------------------------
sudo QEMU_STATIC=qemu-arm-static TARGET_ARCH=armhf ubuntu-image classic -f cloud-image -d --hooks-directory hooks -s bionic -a armhf -O out-tmp -w work gadget/prime
---------------------------------

will cause generate_manifests() function failed. No matter with/without option "--hooks-directory hooks" or not.

## Error message ##
---------------------------------
DEBUG:ubuntu-image:-> [13] generate_manifests
chroot: failed to run command ‘dpkg-query’: No such file or directory
ERROR:ubuntu-image:COMMAND FAILED: ['sudo', 'chroot', '/home/vagrant/vasteras/image-builds/work/root', 'dpkg-query', '-W', '--showformat=${Package} ${Version}\n']
ERROR:ubuntu-image:uncaught exception in state machine step: [13] generate_manifests
---------------------------------

## Other test cases ##

* If the target arch is amd64 and with options "-f cloud-image", the failure will not happened.

* If the target arch is arm64/armhf and with options "-p ubuntu-cpc" without option "--hooks-directory hooks", the failure will not happened.

BUT.. WITH option "--hooks-directory hooks", the failure will happened.

Test cases table as attached (ubunut-image_TestCases.png), hope the table clarifies any confusion.

Hey Soar,

Do you still use this version of ubuntu-image? If you are still building images, can you try ubuntu-image 3.X? This is a complete reimplementation so this bug will probably not appear but the potential underlying issue may still be present.
