[banshee/gio-hardware] [RescanPipeline] Escape Uri val in SQL (bgo#624531)

[Alex Launi <alexlauni src gnome org>]

    [RescanPipeline] Escape Uri val in SQL (bgo#624531)
    
    The Uri LIKE match in the query was hard-coded, which allows for
    un-escaped user input. Use proper SQL parameters instead to ensure a
    safe query construction. Also use Hyena.StringUtil.EscapeLike.
