bootdeploy: support zboot kernel image (MR 44)

As we move towards UEFI on more devices, we want to use systemd-boot and
kernel images built with CONFIG_ZBOOT. However, these images aren't
compatible with existing Android bootloaders. As a result, we must
install both the old vmlinuz image for old bootloaders, and the fancy
new self-extracting EFI image.

When using systemd_boot, use linux.efi as the kernel file name instead
of globbing on vmlinuz*.
