Deiban package: postinst script access /home/*

The postinst script inside the debian package for Discord contains the following code:

# This is probably just paranoia, but some people claim that clearing out
# cache and/or the sock file fixes bugs for them, so here we go
for DIR in /home/* ; do
rm -rf "$DIR/.config/discordstable/Cache"
rm -rf "$DIR/.config/discordstable/GPUCache"
done

In an environment (NFS mounted homes) where root does not have access to /home/ the package fails to install. To install discord I have to remove the postinst script before installing it anywhere.

Ideally, I think this code should be moved to when Discord is started and it detects that the version number has changed.
