Daniel Sampliner a61e43e18e nixos/netdata: copy apps_groups.conf instead of symlink
Currently, it is not possible to configure `apps.plugin` via NixOS
option `services.netdata.configDir."apps_groups.conf"`. This is because
`apps.plugin` explicitly does not follow symbolic links when reading its
configuration from apps_groups.conf[^ref].

This change will copy that file instead of symlinking to address this.

Fixes #255161
