[pbs-devel] [PATCH backup 04/13] media_catalog: use stream_position

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

Fixes the following clippy lint:

```
warning: using `SeekFrom::Current` to start from current position
   --> src/tape/media_catalog.rs:798:23
    |
798 |             let pos = file.seek(SeekFrom::Current(0))?; // get current pos
    |                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: replace with: `file.stream_position()`
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#seek_from_current
    = note: `#[warn(clippy::seek_from_current)]` on by default
```
