Subject: [PATCH] Silence unnecessary `ln -f` warning

Since `cp -a` serves as fallback, there's no need to clutter
the output.

Before:
```
$ sudo update-initramfs -u
ln: failed to create hard link '/boot/initrd.img-6.1.0-3-amd64.dpkg-bak' => '/boot/initrd.img-6.1.0-3-amd64': Operation not permitted
update-initramfs: Generating /boot/initrd.img-6.1.0-3-amd64
```

After:
```
$ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-6.1.0-3-amd64
```
