last version of apcu require extra config

[vbauchart]

just rebuilt my docker image and I get this error:

# docker-compose exec nextcloud occ upgrade
An unhandled exception has been thrown:
OC\HintException: [0]: Memcache \OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)

I dont get time to find out why I get this error but it seems related to https://github.com/nextcloud/vm/issues/2039

So I just add this parameter

echo "apc.enable_cli=1" >> /usr/local/etc/php/conf.d/apcu.ini into my running image to achieve the upgrade.

This bug should be analyse carefuly but I hope this trick will help other people having the same issue
