fix(gitea): Remove cgroup mount to fix LXC startup on some kernels

- Remove cgroup:mixed from lxc.mount.auto (causes "Failed to create
  cgroup at_mnt" error on certain kernel configurations)
- Disable cgroup memory limit since cgroup is not mounted
- Fixes Gitea container failing to start with cgroup mount errors
