Makefile: Remove useless directives

I removed this directives:

- relup: which called makerelease, upload_release and upload_manual
- upload_release: which uploaded the release from Carsten's machine
- upload_manual: which uploaded the manuals from Carsten's machine

We don't need these directives anymore as the release process is
done from orgmode.org server.
