[baobab/wip/vala: 26/53] Pass the directory in the scanner constructor.

[Paolo Borelli <pborelli src gnome org>]

commit cd79a8f4bc52ff0477e2dab6320278a65dc500ec
Author: Paolo Borelli <pborelli gnome org>

    Pass the directory in the scanner constructor.
    
    We decided that scanner is a single use object that is reinstanciated
    every time a new dir is scanned, so passing the directory in the
    constructor makes it more clear.
