[eog] Make sure the libpeas-gtk dependency isn't optimized away

[Felix Riemann <friemann src gnome org>]

commit 46c38b71222b79f711983164a41a4e9d03283016
Author: Felix Riemann <friemann gnome org>
Date:   Wed Nov 19 19:20:03 2014 +0100

    Make sure the libpeas-gtk dependency isn't optimized away
    
    Aggressive linkers could drop the dependency which would
    cause problems using during runtime.
    Based on a patch for the same problem for gedit by Garret Regier.
