fix security hole: don't add an empty element to LD_LIBRARY_PATH1.3

if LD_LIBRARY_PATH was empty, the wrapper script would add the empty
element to the path.

> The trailing colon is treated by ld.so as another item on the list,
> and empty items are treated as '.' (CWD). Therefore, if a user
> executes qtcreator from a directory where there's a library that would
> have normally been loaded from the standard library paths the local
> library would be loaded instead.
> This has the potential effect of arbitrary code execution.
