The rhel-8.4 qcow2 base image already has the grub2-efi-x64 package
installed on its single partition which has files installed to
/boot/efi..., however a partitioned image will have an empty /boot/efi
partition when running 50-bootloader. This means dnf will not install
grub2-efi-x64 when requested and /boot/efi will remain empty.
This commit makes the following changes:
- Refactors redhat bootloader pkg-map for the following:
- Make x86_64/amd64, arm64/aarch64 adjancent so they don't diverge
- Map grub-efi to packages installed to /usr
- Map grub-efi-{arch} to packages installed to /boot/efi
- Removes packages grub-efi-{arch} before installing grub-efi and
grub-efi-{arch}

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__.
