Fix gitea admin deployment to be less brittle

Admin deployment was very timing-dependent: If the server took a while
to set it up, it would always error out while deploying. This commit
adds sufficient grace-time into the admin request call before the error
occurs which should avoid it in most deployments (unless the server is
severely underpowered or over-taxed).

Also fixes admin creation to avoid root usage in the container when it
is not called for.
