Can't identify whether server version 'unknown' is recent

[smcv]

The demo instance at https://fossology.osuosl.org/repo/?mod=browse identifies itself as:

 Version: [unknown], Branch: [master], Commit: [#b04657] 2022/01/07 08:35 UTC built @ 2022/01/07 08:42 UTC 

Similarly, the fossology/fossology:4.0.0-rc1 Docker image on Dockerhub identifies itself as:

 Version: [unknown], Branch: [unknown], Commit: [#unknown] unknown built @ 2021/12/22 06:06 UTC 

and other recent Docker images are similar.

As a result, the version checking in fossology.server cannot identify whether to use old or new APIs:
