[jhbuild] Only run triggers if we actually install

[Giovanni Campagna <gcampagna src gnome org>]

commit 64ce2974c7c2902e53ffb216d7a84f0ae0efcb22
Author: Giovanni Campagna <gcampagna src gnome org>
Date:   Fri Mar 16 23:25:47 2012 +0100

    Only run triggers if we actually install
    
    If we skip phase install for any reason, for example because the
    module is not updated, we don't need to run triggers again.
