Lacking support for LUKS2 devices with dm-integrity

[hardfalcon]

Currently the encryptssh hook does not include the dm-integrity kernel module, which results in an error message when trying to decrypt a LUKS2 device that also uses dm-integrity (for example, if something like cryptsetup --cipher aegis128-random --integrity aead was used to create/encrypt the LUKS2 device).

The encrypt and sd-encrypt mkinitcpio hooks that ship with the Archlinux cryptsetup package were affected by the same issue a few years ago, and the solution was to simply add the dm-integrity module to the encrypt and sd-encrypt hooks:
