fwupd it happens pulls in not only ModemManager but also udisks2, so
there are two daemons running in every container as a result of fwupd's
presence.
Having discussed with the CPC team, it doesn't make sense to include
fwupd in any cloud or container images, unless there's a particular
partner image that's used on baremetal and exposes devices for firmware
updates.
So since fwupd is only a recommends of ubuntu-server, we can and should
just remove this package during the image build.
Leaving the ubuntu-meta task open because we probably do want to
refactor the seeds so that such removals are not necessary during the
image build.

Bug description:
Looking at memory utilization in a pristine Ubuntu lxd container (top
-o RES), I see that ModemManager is running, which I was surprised to
see is present at all in the stock image.
Tracking this I find that fwupd depends on libmm-glib0, which in turn
Recommends: modemmanager.
Libraries in general should not recommend daemons, so it's possible
this should be fixed by libmm-glib0 dropping this Recommends. It
certainly doesn't seem to be a deliberate decision by the Server Team
to have modemmanager installed and running by default on all systems.
