Change I008f8bbc9c8414ce948c601e3907e27764e15a52 has shown that we
build redhat images without the "semange" tool available, which comes
from the policycoreutils-python package (see also
I3f9e2c322d042a5dddba33451c0fc21a4d32a88a).
I403e7806ae10d5dd96d0727832f4da20e34b94c7 added some of the selinux
libraries to yum-minimal for ansible support, but not to others.
Given both these changes, it seems that selinux[-targeted],
libselinux[-python] and policycoreutils[-python] can reasonably
considered part of all base images. Move the selinux related packages
into redhat-common.
This also adds it explicitly to install_test_deps.sh. It was actually
being dragged in by the docker install, but is a required component
for building (should be in bindep, but not there with that yet).

It turns out dnf argparse can't handle negative numbers without "=".
It's actually documented in the man page
--latest-limit <number> ... If <number> is negative skip <number>
of latest packages. If a negative number is used use syntax
--latest-limit=<number>
But who reads that :) This started failing with Fedora 26

Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).
The problem with this is that editable/development installs (pip -e)
do *not* install data_files. Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.
data_files is really the wrong thing to use for what are essentially
assets of the program. data_files install works well for things like
config-files, init.d files or dropping documentation files.
By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from. In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].
We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.
Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.
I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.
Unfortunately, this has to move to work with setuptools. You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.
[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do. Essentially for us it's returning
__file__.
