feat: better initialization script

Rename `tools/build` → `net_services`

`net_services` can be run from anywhere (previously it was not creating
the fs archives in the right place). It also creates the directories
specified in `.env`, generate a self-signed certificate if no
certificate is available, initialize the first Radicale user if missing,
and copy example configuration files if missing for cgit.

`generate_self_signed_cert` has been removed (its code is in
`net_services`)
