prepare-root: Fix composefs docs

In practice in ostree-sysroot-deploy.c we only react to having
`composefs = yes`; the docs mention `maybe` but that never did
anything.

The value is wrong in the code too, but I'm not touching
that here to avoid conflating changes - the main thing to fix
is the docs because here `maybe == no`.
