The ceph-fuse(8) man page describes using the "fusermount" tool to mount
CephFS. This utility is in the "fuse" package. Prior to this change, the
ceph-fuse RPM only depends on "fuse-libs", not "fuse".
The Debian packaging has always depended on the full "fuse" (previously
"fuse-utils") package, so we should make the RPM packaging do the same.
