    Stop using locate in autogen.sh (#702040)
    
    If the gnome-doc-utils package isn't installed and you try to compile
    GParted from git it will fail with this:
    
        $ ./autogen.sh
        /usr/bin/gnome-autogen.sh
        Cannot find file: gnome-doc-utils.make
        You need to install gnome-doc-utils
    
    After installing the gnome-doc-utils package the same error will be
    reported again unless you also update the locate database.
    
    Instead query the full path to the gnome-doc-utils.make file from the
    gnome-doc-utils' pkg-config metadata.
    
    Closes Bug #702040 - very strange gnome-doc-utils check in gparted
