MT#10277 Fix NGCP_VERSION to track all the changes in repo

At the moment deploymnent.sh file on public website
http://deb.sipwise.com/netscript/master/deployment.sh
contains the commit ID of latest file change, but not
the latest commit ID in repository.

From one side it is correct and useful, but from another side
it confuses a lot when you check the verion is Git/Deb and
on public site http://deb.sipwise.com/netscript/

IMHO, it worth to keep them in sync to prevent confusing.
