Blender manpage generator: use blender build date instead of current time.

Browse Source 
It makes much more sense to use the build timestamp of the Blender
binary used to generate that manpage, than the current time.

As a bonus, when Blender building makes use of the SOURCE_DATE_EPOCH envvar
(through CMake, since previous commit), this also propagate automatically
to that man page.

Inspired by D5756 by Bernhard M. Wiedemann (@bmwiedemann), thanks.
