[gnome-photos] Split out the utility GIO wrappers into a separate file



commit a795741973bba7adaadacbd200f9dfc593314535
Author: Debarshi Ray <debarshir gnome org>
Date:   Mon Feb 13 23:11:07 2017 +0100

    Split out the utility GIO wrappers into a separate file
    
    We will need some of them in both the application and thumbnailer
    processes. Moving them into a separate file keeps the build
    dependencies of the thumbnailer in control.
