- adds the systemd-bootaa64.efi file to support UEFI boot for arm64 machines that can do UEFI. - bumps the systemd package from systemd-248.3-2 to systemd-250.5-1 (I couldn't find the arm64 version for systemd-248.3-2 so I bumped them both). The packages come from the arch linux package registries: - amd64: https://archlinuxarm.org/packages/aarch64/systemd - arm64: http://mirror.archlinuxarm.org/aarch64/core/systemd-250.5-1-aarch64.pkg.tar.xz fixes https://github.com/gokrazy/gokrazy/issues/129
