Honour the SOURCE_DATE_EPOCH environment variable 

When the environment variable SOURCE_DATE_EPOCH is set, use it as the epoch of the date to be written in the output.
This allows to build reproducibly packages depending on LDoc to build their documentation, without any change to their code and build process.
See https://reproducible-builds.org/specs/source-date-epoch/
