Add example systems which use an initramfsbaserock/richardmaw/S11159-initramfs
initramfs-test.morph is embedded in the initramfs.write help, so may be removed. The initramfs-x86_64 system is the minimal system with an extra chunk added. The initramfs-utils stratum is required to contain _just_ that chunk, but the "minimal" system is much larger than I would like our initramfs to be (i.e. a statically linked binary using musl), so in future the initramfs-utils stratum may have more initramfs specific content.
