If SOURCE_DATE_EPOCH is defined, use it for copyright year

Using the date from SOURCE_DATE_EPOCH instead of the current date makes
it possible to reproduce a build that was built on a different year:
https://reproducible-builds.org/specs/source-date-epoch/

This is fixing an issue we had while building Tor Browser:
