Subject: [PATCH 2/3] erts: Remove ERLANG_COMPILE_DATE from erl_version.h

Do not generate the ERLANG_COMPILE_DATE timestamp in erl_version.h
with the make_version script to ensure reproducible builds.

Remove the corresponding ERTS_SAVED_COMPILE_TIME option and update
the configure scripts accordingly.
