Rodrigo Campos ce73e1b3e9 docs: Run userns example in /tmp ...

This simplifies the permissions. If it's run on the home, some distros
make the /home/user dir with just permissions for the owner, but we
need +x permissions for others (technically for host user the container
is mapped to, but that is more tricky in this example).

/tmp has the right permissions already, so let's just do the example
there.

While we are there, I just copied the two commands from the runc doc, to
create the rootfs, instead of linking there. Also, I changed the
config.json to include the right path, now that is known.

Having the path fixed makes sure users can't do a mistake when setting
it. This was the cause of #11575 (they were not setting the rootfs as an
absolute path, as documented).
