[PATCH v3 07/11] oeqa selftest uki.py: add aarch64/arm test with systemd based initrd

Use core-image-initramfs-boot with systemd to boot via UKI on
arm/aarch64. Tested on qemuarm, qemuarm64 and genericarm64
on aarch64 build host. The machines have different image
and qemuboot configs so they need to be configured in test.
