nspawn: Add support for sysroot pivoting (#5258)
Add a new --pivot-root argument to systemd-nspawn, which specifies a directory to pivot to / inside the container; while the original / is pivoted to another specified directory (if provided). This adds support for booting container images which may contain several bootable sysroots, as is common with OSTree disk images. When these disk images are booted on real hardware, ostree-prepare-root is run in conjunction with sysroot.mount in the initramfs to achieve the same results.
