[TASK] Fix make scheduler cmd for TYPO3 >6.2

[tbal]

• Determine path to typo3/cli_dispatch.phpsh by looking up
  WEB_DOCUMENT_ROOT env variable which is defined in
  etc/environment.yml and automatically available in
  the app container.
  This makes the 'make scheduler' command work for all
  TYPO3 versions.
• Run container as application user to avoid permission problems.
• Use docker-compose exec instead of docker exec,
  which speeds up the command call, because there is no
  need to determine the container id of the app container
  anymore.

Fixes #139

This does still not work for me:

1. The slash after $WEB_DOCUMENT_ROOT is superfluous and leads to warnings when running make scheduler
2. The command exits with return code 129. This seems to be a known issue with docker-compose, see strange exit status code behavior docker/compose#3379

Below is a suggestion which fixes the issue on top of your change:

Thanks @stucki. I also sumbled upon code 129 in some other cases with docker-compose, but didn't recognized it here. Will integrate this the next days and check my other PRs if there is the need for this workaround too.

Great!

Stuckis suggestion implemented.

Looks good to me, thank you!
