Remove useless lifetime of ArchiveBuilder

`trait ArchiveBuilder<'a>` has a seemingly useless lifetime a, so I remove it. If this is intentional, please reject this PR.

```rust
pub trait ArchiveBuilder<'a> {
    fn add_file(&mut self, path: &Path);

    fn add_archive(
        &mut self,
        archive: &Path,
        skip: Box<dyn FnMut(&str) -> bool + 'static>,
    ) -> io::Result<()>;

    fn build(self: Box<Self>, output: &Path) -> bool;
}
```
