[Simh] Source tar balls for 4.0 beta

[Sevan / Venture37]

Hi,
Would it be possible to resume publishing source tar balls for the
beta releases for simh again, it'd make it easier for packaging up
from things such as ports.
http://simh.trailing-edge.com/sources/
has 3.9.0 beta whilst the github repo is on 4.0 beta.
