pcr: Add abootimg 0.6 from Aur
The Aur package is based on the abootimg-git, Guix and Debian
packages.
While abootimg only supports old Android images format and
its git repository[1] doesn't have new commits since 2012,
the abootimg program is used by diffoscope to produce more
fine grained diffs between two Android boot images.
Without it you end up with a hexdump based diff which isn't
very useful. With abootimg you can really debug and fix
reproducibility issues when creating Android boot images.
Here's what you get between two boot images whose only
difference is due to the timestamps in the gzip command
used to build the images[2]:

And the issue here is not hypothetical as the above show a
real bug preventing tests from working in a tool meant to
add root access by default in Replicant boot and recovery
images. And that bug was really fixed thanks to abootimg.
