Bugfixes:
- Global: update container name regex to ensure that it won't match trailing new line
proot-distro restore: refuse to restore backups where containers don't have rootfs.proot-distro restore: refuse to restore multiple containers at once from a single backup archive.proot-distro restore: skip when the hardlink resolves to a different container than currently being restored, so a crafted archive can't pull a file out of an unrelated existing container.
Also proot-distro restore now will show what container is being restored from backup.
