[rubygems/rubygems] Set SOURCE_DATE_EPOCH env var if not provided.
Fixes #2290.
1. `Gem::Specification.date` returns SOURCE_DATE_EPOCH when defined,
2. this commit makes RubyGems set it _persistently_ when not provided.
This combination means that you can build a gem, check the build time,
and use that value to generate a new build -- and then verify they're
the same.
