Implement ZFS bootonce protocol. We pass zfs-bootonce=t to the next boot stage as a command line argument. Unlike zfsboot -> loader handoff in the BIOS case, we don't use the OS_BOOTONCE_USED. This would require modifications to loader.efi which would only server to make it more complicated. Instead, use the command line parsing interface for the boot1.efi -> loader.efi to pass in the zfs-bootonce kenv that will be needed by rc.d/zfsbe to activate the BE if boot progresses that far.
