FOP-2854: Allow to override CreationDate
    
    Allow to override build date with SOURCE_DATE_EPOCH
    in order to make builds reproducible.
    See https://reproducible-builds.org/ for why this is good
    and https://reproducible-builds.org/specs/source-date-epoch/
    for the definition of this variable.
    
    This patch was done while working on reproducible builds for openSUSE.
