Title: WIP: ship once then exit with code 1 on failure

In order to manage the shipping cycle outside of the assumption that
svlogd is managing the rotation policy, accept the '--once' flag to exit
after a shipping attempt is made.

This is intended to be used when the caller knows that there are new
logs to be shipped.
