#794 last commit unnable to compile if gtk2 over gtk3, missing conditional

[PICCORO Lenz McKAY]

lasted commit as "workaround greeter-gdk can't show background image at gtk3" added a missing function not provided by gtk2, so lxdm seems not able to compile with gtk2:

error: implicit declaration of function 'gdk_window_get_backgroud_pattern'

here i paste a easy patch that solves and able to build agains gtk 2.18 to 2.26 and not only 2.26+
