[salt] Retire Armband Saltstack repos

Provided we take care of the minor consequences of relying strictly
on upstream Saltstack amd64 repos on arm64 (since we don't use RAET,
this means merely installing `python-futures` as a dependency of
`python-tornado` on all minions), we can finally drop our Salstack
arm64 repository.

This implies installing python-futures on:
- FN and VCP VMs (handled via lib.sh pre-patching);
- baremetal nodes (handled via MaaS Curtin template for arm64 now);

While at it, also handle other minor patch cleanup operations:
 * drop `system.linux.system.repo.mcp.armband`, already covered by:
   - lib.sh pre-patching for FN and VCP VM images;
   - maas.region.repositories for baremetal nodes;
 * switch glusterfs PPA repo arch from 'amd64,arm64' to None;
 * drop obsolete patch handling `mcelog` on AArch64;

+Subject: [PATCH] linux.system.repo: Drop arch for openstack repo
+
+Now that mcp-repos mirror has arm64 packages too, we can either extend
+the current architecture list or just drop it and let APT figure it
+out.
+
+Extending the arch list to 'amd64,arm64' would lead to doubling repo
+metadata downloads on all archs, while dropping it will allow APT to
+only download the repo metadata for the current system arch.
+
+To keep old behavior for amd64 and prevent multiple downloads, let's
+just drop the 'architectures' field.
