stages(copy): allow copying from a mount or the tree

Browse source 
It seems like an artifical limitation to prevent copying from a mount
or from one location in the tree to another. It just so happens we need
this functionality when building CoreOS images because we want to take
a file embedded in the OSTree at a location and copy it to another
location in the tree. The particular example here is we want to copy
/usr/share/coreos-assembler/platforms.json -> /boot/coreos/platforms.json
See https://github.com/coreos/coreos-assembler/pull/3709

Allowing to copy from/to the tree we can now do something like:

```
- type: org.osbuild.copy
  options:
    paths:
      - from: tree:///usr/share/coreos-assembler/platforms.json
        to: tree:///boot/coreos/platforms.json
  mounts:
    - name: ostree.deployment
      type: org.osbuild.ostree.deployment
      options:
        deployment:
          ref: ostree/1/1/0
          osname:
            fedora-coreos
```
