The current logic in ima-evm-rootfs.bbclass does not guarantee
ima_evm_sign_rootfs is the last function in IMAGE_PREPROCESS_COMMAND
by appending to it, for instance, if there are other "_append" being
used as it's the case in openembedded-core/meta/classes/image.bbclass:
| IMAGE_PREPROCESS_COMMAND_append = " ${@ 'systemd_preset_all;' \
| if bb.utils.contains('DISTRO_FEATURES', 'systemd', True, False, d) \
| and not bb.utils.contains('IMAGE_FEATURES', 'stateless-rootfs', True,
| False, d) else ''} reproducible_final_image_task; "
and ima-evm-rootfs should be in IMAGE_CLASSES instead of in INHERIT
since that would impact all recipes but not only image recipes.
To fix the above issues, we introduce a ima_evm_sign_handler setting
IMA/EVM rootfs signing requirements/dependencies in event
bb.event.RecipePreFinalise, it checks 'ima' distro feature to decide if
IMA/EVM rootfs signing logic should be applied or not.
Also add ima-evm-keys to IMAGE_INSTALL.

data/debug-keys will be reused for demo modsign keys, so rename
IMA_EVM_BASE to more generic INTEGRITY_BASE.
