Move exclusions of trousers-lib and iproute-tc to minimal-common

These are aiming to leave some weak dependencies out of minimal
images, it seems. From @core, gnutls recommends trousers which
requires trousers-lib, and iproute recommends iproute-tc.

However, both are *hard* dependencies of things that include
fedora-disk-base.ks. fedora-disk-workstation.ks includes
fedora-disk.base.ks and fedora-workstation-common.ks, so it
installs the Workstation package set, from which gnome-boxes
ultimately requires iproute-tc and NetworkManager-openconnect
ultimately requires trousers-lib.

Prior to the change I recently got merged into DNF, DNF would
silently drop gnome-boxes and NetworkManager-openconnect from
the Workstation disk image because of this. With the change, it
errors out on creation of the image.

To make the image compose again and actually include the right
packages, let's move the exclusions to fedora-minimal-common.ks,
where they make more sense anyway. This does mean the packages
will be pulled into other non-minimal images even if they're
not strictly required there, but that doesn't seem like a big
problem.
