[gnome-boxes] Don't pass Ctrl/Alt keys to search entry

[Alexander Larsson <alexl src gnome org>]

commit 62747caf1d6b0661b284f26cc9299dbc630c51b7
Author: Alexander Larsson <alexl redhat com>

    Don't pass Ctrl/Alt keys to search entry
    
    These mean nothing to the entry in general, but do override
    any possibility of handling such events as keyboard accelerators
    up the widget hierarchy.
