[TYPO3-core] FYI #11986: dynamic update of translation status im EM is broken

[Rupert Germann]

FYI: the following changes have been committed to trunk and 4-2 branch 
as a no-brainer

trunk rev 5990
4-2 branch rev 5992


Problem:
when updating translations with the extension manager the dynamic update 
of the progress bar and the display of messages during the update is broken.
The update of translations works - this affects only the output.
Reason for this is the output buffering/compression which is activated 
in init.php

Solution:
end output buffering by adding ob_end_flush();
