ZEPPELIN-815 don't create a sub shell for the runner
### What is this PR for?
This pull request is supposed to fix ZEPPELIN-815. The issue is that one
cannot stop Zeppelin by sending a signal, because it starts the runner in a sub
shell. The pull request starts the runner in the same process as the
`zeppelin.sh`, making it react to signals.
### What type of PR is it?
Improvement
### Todos
* [ ] - Task
### What is the Jira issue?
https://issues.apache.org/jira/browse/ZEPPELIN-815
### How should this be tested?

- Get PID of the `zeppelin.sh` process
- Send SIGINT (`kill -SIGINT <pid>`) to the `zeppelin.sh` process
- Observe that Zeppelin is stopped
### Screenshots
none
### Questions:
* What is the reason to put an exec into a sub shell in the first place?
