Dusty Mabe ce8408a9c6 mounts: support mounting partitions 
This allows us to map in a whole disk as a loopback device with parition
scanning rather than slicing up the disk and creating several loopback
devices. Something like this:

```
      - type: org.osbuild.copy
        inputs:
          tree:
            type: org.osbuild.tree
            origin: org.osbuild.pipeline
            references:
              - name:tree
        options:
          paths:
            - from: input://tree/
              to: mount://root/
        devices:
          efi:
            type: org.osbuild.loopback
            options:
              filename: disk.img
              start:
                mpp-format-int: '{image.layout[''EFI-SYSTEM''].start}'
              size:
                mpp-format-int: '{image.layout[''EFI-SYSTEM''].size}'
          boot:
            type: org.osbuild.loopback
            options:
              filename: disk.img
              start:
                mpp-format-int: '{image.layout[''boot''].start}'
              size:
                mpp-format-int: '{image.layout[''boot''].size}'
          root:
            type: org.osbuild.loopback
            options:
              filename: disk.img
              start:
                mpp-format-int: '{image.layout[''root''].start}'
              size:
                mpp-format-int: '{image.layout[''root''].size}'
        mounts:
          - name: root
            type: org.osbuild.xfs
            source: root
            target: /
          - name: boot
            type: org.osbuild.ext4
            source: boot
            target: /boot
          - name: efi
            type: org.osbuild.fat
            source: efi
            target: /boot/efi
```

now becomes a little more simple:

```
      - type: org.osbuild.copy
        inputs:
          tree:
            type: org.osbuild.tree
            origin: org.osbuild.pipeline
            references:
              - name:tree
        options:
          paths:
            - from: input://tree/
              to: mount://root/
        devices:
          disk:
            type: org.osbuild.loopback
            options:
              filename: disk.img
              partscan: true
        mounts:
          - name: root
            type: org.osbuild.xfs
            source: disk
            partition:
              mpp-format-int: '{image.layout[''root''].partnum}'
            target: /
          - name: boot
            type: org.osbuild.ext4
            source: disk
            partition:
              mpp-format-int: '{image.layout[''boot''].partnum}'
            target: /boot
          - name: efi
            type: org.osbuild.fat
            source: disk
            partition:
              mpp-format-int: '{image.layout[''EFI-SYSTEM''].partnum}'
            target: /boot/efi
```
