Add git-archive-all

Install it in Git's exec dir, so `git archive-all` will do the right
thing.

Add the `GIT_ARCHIVE_CMD` variable to `pgxn-bundle` To have it use
git-archive-all, run

```sh
GIT_ARCHIVE_CMD=archive-all pgxn-bundle
```

Also add `cmake` and `libarchive-tools` to the image and properly quote
variables in `pgxn-bundle`.
