stratosphere debian package fixes

The debian package is working quite well actually. I just fixed some minor naming issues.
(build it with `mvn clean package -DskipTests -Pdebian-package`)
```
ubuntu@ubuntu-VirtualBox:~$ sudo dpkg -i stratosphere-dist_0.5-SNAPSHOT.deb 
[sudo] password for ubuntu:
