tools: Fix tag for eve-mkimage-iso-efi

Commit ee15f4d introduced changes to fetch
the eve-mkimage-iso-efi container for the right target architecture, the
fix was needed to generate ISO images for arm64. However, the ARCH prefix
was missing for the linuxkit pkg tag resolution. This commit adds the ARCH
prefix just as it's done in the tools/parse-pkgs.sh script.
