Use current working dir instead of /tmp

While the docu on https://www.zulip.org/server.html says:
```
cd /root/zulip
./scripts/setup/install
```
This script downloads the `python-django-guardian_1.3-1~zulip4_all.deb` file to current working dir (`/root/zulip` if you follow the docu), but tries to install it from /root/.
This fails obviously. So i changed the download location to /tmp/.
