debian: ceph-cfuse: move ceph from Recommends to Suggests
on a standalone fuse client ceph serverside is not needed. if it's
"Recommended" the default behaviour is to install it too. Move it to "Suggests"
that it's not installed by default if one installs just ceph-fuse.
from debian policy:
Suggests:
This is used to declare that one package may be more useful with one or more
others. Using this field tells the packaging system and the user that the listed
packages are related to this one and can perhaps enhance its usefulness, but
that installing this one without them is perfectly reasonable.
