Just to avoid users from trying this with a to new (untested) php version

* Moved the check logic to 1 place
* All directly callable scripts just require this on top
* exit hard (-1) so we know scripts won't continue
* Return status 500 so no sync clients will try fancy stuff

* the setup check is still there

In case of fatal php errors and other unhandled exceptions no html error page is expected to be displayed in the console

Probably nice for the people that contributed to 9.0 to see themselves in the AUTHORS file :)

* fixes owncloud/updater#252

* this changes into the ownCloud root directory and then should run just fine
* avoids weird error messages that are caused by this

The config directory must be taken from OC::$configDir

Minor fix

 - Remove uneeded slash in the configdir path.

In regard to a recent rant on social media where users complained about us to have broken the command line tool. Guess reading the documentation is hard…

Owncloud complains if the user runs a shell script with a user other than the user that owns `config/config.php`. The error message does not reflect this, and instead speaks about the web server user. Related issue: #15920 .

This reverts commit 6a1a4880.
