initramfs-tools is not able to include all the needed modules

Background

On Apertis v2026dev2 and only for armhf initramfs-tools is unable to include all the needed modules, making the system unbootable.

After debugging, the issue seems to be caused by the utility dracut-install failing to traverse directories.

As example, the following command on armhf does not include any module.

/usr/lib/dracut/dracut-install -v --debug -D /root/ram --kerneldir /lib/modules/6.12.22-armmp --firmwaredirs /lib/firmware/updates/6.12.22-armmp:/lib/firmware/updates:/lib/firmware/6.12.22-armmp:/lib/firmware -o -m =drivers/ata

Similar command on amd64 and arm64 works fine.
