Implement support for the SOURCE_DATE_EPOCH environment variable as
specified by reproducible-builds.org. When set, this variable overrides
the current timestamp in the Release file's Date and Valid-Until fields,
enabling reproducible filesystem publishes.
- Read SOURCE_DATE_EPOCH environment variable in Publish()
- Use the epoch timestamp for both Date and Valid-Until fields
- Gracefully fallback to current time if unset or invalid
- Add comprehensive tests for valid and invalid SOURCE_DATE_EPOCH values

The root problem was 4.3.5a comparing less than 4.3.5-rc1-1 by aptly
According to debian "4.3.5a" > "4.3.5-rc1-1"
This is because dpkg splits hyphen for revision at the first hyphen,
whereas aptly was splitting at the last hyphen which is different from
dpkg's behaviour.

Perhaps this wasn't detected as there was broken tests in the repository
since the initial commit of aptly. This also fixes those tests
Enabling coverage near-doubles the incremental build time and adds
overhead to individual tests on the order of **5-10x** or more. It's not
essential to have this for quick local system-test runs, so add an option
to disable it.
When using rootless podman, the *current user* gets mapped to uid 0,
which results in the aptly user being unable to write to the build
directory. We can instead map the current user to the corresponding uid
in the container via `PODMAN_USERNS=keep-id`, which matches up with what
docker-wrapper wants...but then that will *enter the container as the
current uid*, which messes with the ability to set permissions on
`/var/lib/aptly`. That can be fixed by explicitly passing `--user 0:0`,
which should be a no-op on docker (since the container's default user is
already root).
Additionally, this adds `--security-opt label=disable` to avoid
permission errors when running on systems with SELinux enforcing.
