[gnome-software/1111-version-history-box: 68/71] src: Move time-to-string function to gs-common

[Phaedrus Leeds <mwleeds src gnome org>]

commit 130832d69c19357ee4c0a1785c331e1c47dc80a3
Author: Phaedrus Leeds <mwleeds endlessos org>
Date:   Wed Feb 3 18:41:44 2021 -0800

    src: Move time-to-string function to gs-common
    
    This will allow it to be reused in later commits. Also change it to be
    more in line with how time spans are displayed in the mock-ups for the
    version history widget, e.g. "5 weeks ago" instead of "25 May 2012".
    This code is based on code in gnome-shell's js/misc/util.js.
