Add a --source-date-epoch flag, defaulting to $SOURCE_DATE_EPOCH if set,
which sets the created-on date and the timestamp for the new history
entries, but does not default to modifying the timestamps on contents in
new layers.
Add a --rewrite-timestamp flag, which "clamps" timestamps in the new
layers to not be later than the --source-date-epoch value if both
the --rewrite-timestamp and --source-date-epoch flags were set.

cause us to pay attention to mirroring settings for images used by this
set of tests.
