Allow to override resource file date 

because some packages create resource input files at build time
and thus get the build date embedded in binaries,
so that they differ for each build.

See https://reproducible-builds.org/ for why this matters
and https://reproducible-builds.org/specs/source-date-epoch/
for the definition of this variable.
