Subject: [PATCH] Ensure unit is journaled for short-lived or oneshot processes

In the time it takes to process incoming log messages, the process we

are logging details for may exit. This means the cgroup data is no

longer available from '/proc'. Unfortunately, the way the code was

structured before, we never log _SYSTEMD_UNIT if we don't have this

cgroup information.

Add an else if case that allows the passed in unit_id to be logged even

if we couldn't capture cgroup information. This ensures a command like

`journalctl -u run-XXX` will return all log messages from a oneshot

process.
