Bug#774915: live-tools: fails to upgrade from 'wheezy': dpkg-divert: error: rename involves overwriting `/usr/bin/uptime' with different file

[Andreas Beckmann <anbe@debian.org>]

Followup-For: Bug #774915

Cleanup of obsolete diversions needs to be performed in postinst.

This is a completely untested suggestion for live-tools.postinst to
properly clean up the obsolete uptime diversions.
