zstd compressed nvidia drivers not included in initramfs

[Benjamin Drung]

/usr/share/initramfs-tools/hooks/framebuffer-nvidia looks only for *.ko modules:

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

But the kernel modules are zstd compressed on mantic:

```
# ls /lib/modules/6.5.0-5-generic/updates/dkms/ -1
nvidia-drm.ko.zst
nvidia-modeset.ko.zst
nvidia-peermem.ko.zst
nvidia-uvm.ko.zst
nvidia.ko.zst
```

does it work with lrm (aka the default configuration)?

[Benjamin Drung (bdrung)]

lrm? I am using a minimal schroot environment with all default settings.

[Dimitri John Ledkov (xnox)]

@bdrung please install drivers using ubuntu-drivers.

I have no nvidia hardware. I was trying to install nvidia-graphics-drivers-535 in a chroot to measure the generated initramfs size.
