Fixes and improvements for SWUpdate images, kernel/config update

Changes in v2:
- add plugin fix for empty command line case

Various update and enhancement I try to summarize here:
- qemu-arm64 enabling for SWUpdate/secure boot using the UEFI pattern
- update to EFI Boot Guard 0.11
- switch to unified kernel images built by EFI Boot Guard
- fix for verity setups with CONFIG_DM_VERITY=m
- improve error handling when mounting /etc overlay
- update to latest CIP kernels and cip-kernel-config
