[evince] browser-plugin: Replace gdkwayland.h include with gdk.h

    browser-plugin: Replace gdkwayland.h include with gdk.h
    
    GDK_WINDOWING_WAYLAND macro is defined in gdkconfig.h, not gdkwayland.h,
    so including gdk.h is sufficient. This also fixes build on systems not
    supporting Wayland.
