Related to nextcloud/docker#1344 & #24914

The cron.php file has a check to ensure the ownership... that fails if using nextcloud in containers with NFS as backend storage for /var/www/html with proper all_squash,anonuid=82,anongid=0 to match www-data:root ownership.

https://github.com/nextcloud/server/blob/master/cron.php#L99-L104

Describe the solution you'd like
Some config.php setting to disable the check would be nice.

Describe alternatives you've considered
As a workaround, I've just modified the file to skip the exit(1) call
