aarch64: Add kpti=off similar to x86_64 nopti
arm64 kernels use a different kernel option (kpti=off vs nopti) to disable PTI, so sync the two platform configurations. Conveniently, this also bypasses kernel 4.15 issues described in [1], so apply the kernel option customisation via MaaS too, to allow aarch64 deployments to bootstrap using 4.15 kernel (with the downside of these args being duplicated by Salt later in HA scenarios). PTI is now disabled for baremetal nodes (via MaaS, no matter the scenario) and/or for kvm/cmp hosts (in HA scenarios only). While at it, install missing thin provisioning tools in aarch64 bootstrap image for MaaS deploy stage to succeed.
