fix: Make dists generation nearly atomic

There is a time frame where the `Packages` files are updated, but the
`Release` files are not updated yet. To reduce the time frame where the
archive is in an inconsistent state, generate the update for the `dists`
directory in a temporary directory. Once the update is prepared, use
`os.rename` to move the old directory away and move the newly prepared
directory in place. There is a tiny time frame between both `os.rename`
where the directory is missing, but this time frame should be small
enough to be not relevant in practice.

To make the `dist` directory generation truly atomic, symlinks need to
be used. Even after that there could be a race on the client side: The
client could fetch the `Release` file, then the `dists` directory could
be updated, then the client tries to fetch the `Packages` file.

feat: Generate InRelease files in addition to Release.gpg

The Apport system tests often fail with:

```
W:GPG error: http://ddebs.ubuntu.com jammy-updates Release: The following signatures were invalid: BADSIG C8CAB6595FDFF622 Ubuntu Debug Symbol Archive Automatic Signing Key (2016) <ubuntu-archive@lists.ubuntu.com>
E:The repository 'http://ddebs.ubuntu.com jammy-updates Release' is not signed.
```

So generate an `InRelease` file in addition to `Release.gpg`.
