feat: disable non sa logins during recovery (#16)

Sybase server port is opened while it is not completely setup (with
multiple devices setup).

Client using the image should not use SA account but instead use a non
SA account so that the login will work when sybase becomes ready.

- [x] set "enable logins during recovery" cf to 0
- [x] fix log by replacing "sybase started" to "docker-sybase started"
- [x] add basic docker-compose example
- [x] clean README
