After we move inspection code to the daemon, the library will no
longer have access to ‘struct inspect_fs’, and so we won't be able to
prefix downloads with the "root filesystem number".
Just remove this prefix (it's internal only). However it does mean
that this function can no longer cache downloaded files.
