Bug#740823: alignment=center|right doesn't work with width=0

[Yuri D'Elia]

Package: dunst
Version: 1.0.0-2
Followup-For: Bug #740823

I wrongly filed this fix under the wrong bug report before, sorry for the noise.

The problem is caused by pango not knowing the final layout width when 
rendering.
The attached patch fixes the problem.
