Recently we changed the region from DA (Dallas) to DC (Washington),
because there are more ARM64 servers available. Reflect this change in
the new pipeline too.
This made no difference back when lib was a symlink to lib64, but now that they are separate,
libs belongs in /usr/lib64. This mostly doesn't show up because ldconfig configures the ld.so cache
to include both locations, but when updating from an older release ld.so.cache is out of date.
Unfortunately ld.so.cache does not get updated until after multipathd, which causes
multipathd to dump core. This may also affect other packages that need access to
libgcc early.

`c3.large.arm64` instances of Equinix Metal are available in metro
either `DA` or `DC`. However, recently arm64 CI builds started to fail
due to too few servers available in the DA metro. As the DC metro has
more servers available, let's change metro to DC.
How to check how many servers are available in a specific metro:
```
curl -X POST \
-H "Content-Type: application/json" -H "X-Auth-Token: ..." \
https://api.equinix.com/metal/v1/capacity/metros \
-d '{"servers": [ { \
"metro": "dc", \
"plan": "c3.large.arm64", \
"quantity": 34 \
} ] }'
curl -X POST \
-H "Content-Type: application/json" -H "X-Auth-Token: ..." \
https://api.equinix.com/metal/v1/capacity/metros \
-d '{"servers": [ { \
"metro": "da", \
"plan": "c3.large.arm64", \
"quantity": 17 \
} ] }'
```
When the build system runs the packages jobs for both architectures in
parallel and has to create a new tag, tagging fails due to the race in
the tagging.
Move the git tagging to its own script that is run from a new top-level
job that starts the packages jobs for both architectures.
When the specified remote contains a same-named branch as origin,
the checkout fails with "fatal: 'X' matched multiple (Y) remote
tracking branches".
Add the remote name as prefix to make the reference unambiguous.
While we moved the arm64 tests to lxc containers, amd64 stayed on VMs
which were not easy to scale up.
Now the GitHub Action runner is running on lxc containers and we can
spawn more VMs in parallel because it has no memory limit.
There is some cruft left after grub hashes generation. After the
contents are zipped into archive, they don't need to be around any
more.
Try to remove the rootfs directory after unmounting the
image. disk_util can recreate it again if there is a need for it.
Remove the build directory used for generating ACI images - it's not
needed after successful installation.
The image comparison was done against the old release in the channel
we release to instead of the previous release with the same major
version. This means when a channel transition happens we see a large
diff instead of the diff against the previous release. While not bad
for finding problems, this is normally not needed. However, we want
to have two changelogs generated, one against the old release in the
channel we relese to and one against the previous release with the same
major version when a transition happens. There was no changelog
printing yet, and this is added now.
