nicer date format and support for SOURCE_DATE_EPOCH in LXC_GENERATE_DATE

Using $(date) for LXC_GENERATE_DATE has various flaws: * formating depends on the locale of the system we execute configure on * the output is not really a date but more a timestamp Let's use $(date --utc '+%Y-%m-%d') instead. While at it, also support SOURCE_DATE_EPOCH [1] to make the build reproducible [1] https://reproducible-builds.org/specs/source-date-epoch/Signed-off-by: Evgeni Golov <evgeni@debian.org>
