fsck: Mention file system name in failed identification warning

Browse Source 
`update-initramfs` might be unable to identify the file system type of
the root file system:

```
$ update-initramfs -u
update-initramfs: Generating /boot/initrd.img-5.15.0-1059-kvm
W: Couldn't identify type of root file system for fsck hook
```

This error message can be confusing and misleading for the user. The
Ubuntu bug reported initially assumed it to be a bug in initramfs-tools
but later found out that the file system missed the label.

Mention the file system name in failed identification warning to help
the user finding the reason.
