fix: patch out FileUtils.chown for rootless Alpine containers

The FileUtils.chown calls in openvoxserver-ca fail in rootless containers
because the process lacks CAP_CHOWN. The directory ownership is already
handled correctly by the g=u / SGID permission pattern.

This is the same approach used in the openvox-operator project.
