init: nvidia integration - Exclude repos from bind-mounting (#1503)

When used on a Universal Blue OS like bluefin, the repo configurations
are available at `/run/host/etc/yum.repos.d/`. Repos that contain the
name nvidia are incorrectly bind-mounted into the container and causes
weird errors on boxes using yum and dnf.
