Extensions loaded via mounted volume have incorrect permissions

[jortkoopmans]

When mounting a volume for extensions, to /tmp/extensions/, the files are copied by start.sh with incorrect permissions, ending up being root owned in /usr/share/nginx/html/extensions/*.

I'm failry sure this is caused by the copy command being executed by root, not preserving the owner:

cp -r /tmp/extensions/* /usr/share/nginx/html/extensions/

My guess is that it would be solved by:

cp -rp /tmp/extensions/* /usr/share/nginx/html/extensions/

Temporary workaround: go into the container and fix the permissions on the extensions at /usr/share/nginx/html/extensions/
