install: Improve support for non-default puppet rules.

Browse Source 
Previously, the install script would fail if you passed various
non-default puppet rules, since the code to configure and restart
services that runs later on in the install script largely ran
unconditionally, regardless of whether the relevant service was
actually installed on the target system.

This should make the main install script reusable for installing
e.g. a dedicated Postgres server for use with Zulip.
