pveceph: ensure ceph-fuse gets uptdated when installing ceph server
as we depend on ceph-fuse elsewhere (pve-storage) this gets installed
from Debians repositories with the Ceph 10 version.
So ensure that an up to date version, from our current supported Ceph
release, gets installed when doing `pveceph install` else you may
fall into certain issues which would have been already resolved with
a newer version.
