build: include journal errors and adsys logs in apport report (#949)

To reduce the back and forth with bug reporters, update our apport hook
to attach more helpful information to reports.

We now include journal errors around the report timestamp (+/- 10
minutes), and any journal messages containing "adsys" -- this includes
logs emitted by the service and possibly more messages referring to
adsys which do not necessarily come from the service.

Fixes #944 / UDENG-2489
