fix: handle rootless redis-session.ini

[tlvince]

Warns the user to mount redis-session.ini when running not running as root.

If this looks good, I'll duplicate to the other entrypoint scripts.

Closes #763.

Hey @tlvince, you should make the change to ./entrypoint.sh not ./25/apache/entrypoint.sh and when before testing run the ./update.sh script.

I have been doing something like this to run a quick test 🙂

./update.sh && docker build --tag 'nextcloud:25-fpm' 25/fpm && docker run --rm nextcloud:25-fpm

Ah, great! Updated, thanks.

Well, it's not a fix just a more verbose info. It shouldn't hurt to add it but it needs rebasing.
