initramfs-tools hook does not support zstd-compressed kernel modules

[Benjamin Drung]

librem-ec-acpi-dkms in librem-ec-acpi uses:

```
    for kmod in $(find "${MODULESDIR}/${dir}" ${exclude:-} -name "$pattern*.ko" -print); do
        manual_add_modules $(basename ${kmod} .ko)
    done
```

vmxnet in open-vm-tools uses:

```
if find "${DESTDIR}"/lib/modules -name pcnet32.ko >/dev/null; then
 manual_add_modules vmxnet
fi
```

Ubuntu 24.04 (noble) ships kernel modules compressed (e.g. pcnet32.ko.zst) and those snippets will not find these compressed modules.

Be also aware of the change to manual_add_modules done in bug #2065180

From the analysis in the MP, the code in question is vestigial. I let Debian know and they've removed the file. When they put out a new release it will automatically sync in here.

Since the code is non-operational there's no point backporting the cleanup, so I'll close out the noble task.

[Bryce Harrington (bryce)]

I'm marking the oracular task as fix committed since the fix is committed in Debian and as mentioned will appear in the archive on the next sync/merge of the package.

Upstream has released a new version so potentially we'll get it when Debian updates to that.
