exit status: Introdude Debian::Dgit::ExitStatus

No callers yet.

Also, no version for dgit-infrastructure.  The one perl script in
dgit-infrastructure that cares a lot about its exit status
(dgit-repos-policy-debian) already has an END { } and uses _exit,
which is a bit like our approach here, but simpler.
