allscenarios-linux.conf: hardening, remove NFS

We do not use NFS in the image, nor in any of the blueprints. An unused service
is a potential security issue, so we remove it.

In addition to expected DISTRO_FEATURES/IMAGE_FEATURES, we need to remove a
dependency to the packagegroup-core-device-devel that includes nfs. This
package is included in poky.conf for all qemu builds, but is not needed and
has been removed from Poky [1] in August 2020.
