Merge bitcoin/bitcoin#32678: guix: warn and abort when SOURCE_DATE_EPOCH is set

5c4a0f8009 guix: warn and abort when SOURCE_DATE_EPOCH is set (will)

Pull request description:

  Fixes: #29935

  Current behaviour will by-default use SOURCE_DATE_EPOCH from the environment without warning. This breaks the default reproducibility from a guix build.

  Warn when and exit when this variable is set, and
  FORCE_SOURCE_DATE_EPOCH is unset.
