Fix fcos-base-image Containerfile (#16)

nfs-utils-coreos conflicts with nfs-utils, dependency of several packages.

Although some packages can be removed in favor of running their services on top of containers (see coreos/fedora-coreos-tracker#572), nfs-utils is still a dependency for other packages we need to install in the host.
