puppet: Pass zulip scripts path as a FACTER to puppet.

Browse Source 
This makes it possible for the Puppet codebase to access the path to
the relevant /home/zulip/deployments type directory that puppet was
run from, which in turn makes it possible to safely call scripts from
here.

Based on work by Rein Zustand.
