Title: gitian: build linux boost without zlib support

Boost iostreams was picking up zlib in some build environments.

We do not need zlib support in boost::iostreams so disable it.

This normalizes the gitian boost build between build environments by forcing a setting instead of auto-detecting.

Fixes the non-deterministic issue in #3725
