Fixes the suspicious_open_options clippy lint, for example:
```
warning: file opened with `create`, but `truncate` behavior not defined
--> src/api2/tape/restore.rs:1713:18
|
1713 | .create(true)
| ^^^^^^^^^^^^- help: add: `.truncate(true)`
|
= help: if you intend to overwrite an existing file entirely, call `.truncate(true)`
= help: if you instead know that you may want to keep some parts of the old file, call `.truncate(false)`
= help: alternatively, use `.append(true)` to append to the file instead of overwriting it
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#suspicious_open_options
```
