ceph-volume: add "packaging" to install_requires

in 0985e201, "packaging" was introduced as a runtime dependency of
ceph-volume, and `ceph.spec.in` was updated accordingly to note
this new dependency. but the debian packaging was not updated.

in 80edcd40, the missing dependency was added to debian/control as
one of ceph-volume's runtime dependency.

but dh_python3 is able to figure out the dependencies by reading
the egg's metadata of the ceph-volume python module. and as a
python project, ceph-volume is using its `setup.py` for
tracking its dependencies.

so in order to be more consistent, and keep all of its dependencies
in one place, let's move this dependency to setup.py . as the
packagings in both distros are able to figure the dependencies
from egg-info.
