collab: Add missing dependencies for building Docker image (#17893)

This PR adds some missing dependencies to the Docker image that are now
needed in order to build collab.

When trying to build the docker image at
761129e3739efacb7b8763eaa0fa8a109e935447 it fails with the following
error:

```
985.3   = note: /usr/bin/ld: cannot find -lxkbcommon: No such file or directory
985.3           /usr/bin/ld: cannot find -lxkbcommon-x11: No such file or directory
985.3           collect2: error: ld returned 1 exit status
985.3           
985.3 
985.4 error: could not compile `collab` (bin "collab") due to 1 previous error
```

The last time we built the Docker image for collab was:

- Staging: 4f408ec65a3867278322a189b4eb20f1ab51f508
- Production: fc4c533d0a8c489e5636a4249d2b52a80039fbd7
