[REVIEW 3-6] Hide information about failure during very early startup a little less

Not that epic early failure should ever happen anyway (cf 
<https://bugs.freedesktop.org/show_bug.cgi?id=51685#c6> "crash on start 
/ duplicate component registration issue ...").

But if it /does/ happen, 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=91404d1d379fbdc3b1c7286dafd2519b68b08c97> 
"Hide information about failure during very early startup a little less" 
is a helpless attempt at getting at least a little more useful 
information than just "doesn't start" (at least on Linux and Mac OS X, 
where one could ask an affected user to run soffice from a shell and see 
if it reports anything to stderr).

Please consider for integration into libreoffice-3-6.  (I consider the 
fix very low risk.)
