Snapshot package feeds not updated

[piaddic7ed]

I ran into an issue using the snapshot imagebuilder for ramips/mt7621 (see below).
From what I can tell the package feeds were not updated with the latest build.
mipsel_24kc is one day old and x86_64 is even 3 days old as of writing this post.

Collected errors:
 * pkg_hash_check_unresolved: cannot find dependency libubox20220927 for mtd
 * pkg_hash_fetch_best_installation_candidate: Packages for mtd found, but incompatible with the architectures configured
 * opkg_install_cmd: Cannot install package mtd.
 * satisfy_dependencies_for: Cannot satisfy the following dependencies for mtd:
 * 	libubox20220927
 * opkg_install_cmd: Cannot install package mtd.

They get updated just fine, but due to the two-step buildbot infra, the ABI versioned packages may take 1-3 days to be fully in sync. (Ubox was updated 29 hours ago, so the build artefacts are possibly still not yet fully synced.)

@hnyman thanks for your advice. I didn't know about the two phase process. I'll be watching buildbot package builds from now on.
