[gnome-sound-recorder/wip/jtojnar/es6: 2/5] Use var instead of let or const

[Jan Tojnar <jtojnar src gnome org>]

commit e3e1d9b9346d24463fbb90d4a39a21251332999b
Author: Jan Tojnar <jtojnar gmail com>
Date:   Fri Jan 18 00:39:31 2019 +0100

    Use var instead of let or const
    
    Now only for module members used externally, I marked them with a comment.
    Hopefully we will be able to get rid of var once GJS implements ES6 modules.
