ntp: Reproducible build: Respect SOURCE_DATE_EPOCH

If a SOURCE_DATE_EPOCH is set in the environment, use that date in the build
version string, otherwise use the current build date.
See https://reproducible-builds.org/docs/source-date-epoch/

Should GNU date options fail, try BSD date options as a fall-back.
This patch can potentially be pushed upstream for use on Mac OSX or OpenBSD,
though it has not been tested on OSX or any BSD platform.
