systemd broadcast message spam during test run

[Michael Foord]

During a full test run on vivid there is systemd broadcast message spam (in one large chunk) to all open terminal windows.

e.g.
ok github.com/juju/juju/cmd/envcmd 0.160s

Broadcast message from systemd-journald@UbuntuBox (Mon 2015-05-18 16:21:57 BST):

[6231]: 2015-05-18 15:21:57 DEBUG juju.apiserver apiserver.go:273 <- [7] machine-1 {"RequestId":6,"Type":"NotifyWatcher","Id":"2","Request":"Stop","Params":"'params redacted'"}

Note that this only happens when running the juju test suite on a host running systemd. Normal use of juju does not appear to manifest the "stdout spam".

The message implies that some log entries are getting written to stdout, which systemd catches and writes to its log (and stdout).
