[gtk+] Remove tests/testtreemenu

[Daniel Boles <dboles src gnome org>]

commit 88ae92050e9f2379246fb6cceea1575cf7a7e569
Author: Daniel Boles <dboles src gnome org>

    Remove tests/testtreemenu
    
    Since GtkTreeMenu became a private class only used by GtkComboBox, all
    this test actually did was to show a ComboBox constructed with a custom
    CellArea. Now that the latter is no longer possible, the test just shows
    a handful of settings that do nothing. Just test GtkComboBox directly.
