autopkgtest aa-check fail on xenial and vivid+overlay on armhf

[Jean-Baptiste Lallement]

aa-check test fails in autopkgtest [1] on xenial and vivid+overlay on armhf

The error from the log is:

adt-run [06:30:03]: test aa-check: [-----------------------
 content-hub-test-ok failed
virtual void com::ubuntu::content::Hub::register_import_export_handler(com::ubuntu::content::ImportExportHandler*) Failed to register object for: "content-hub-test-importer"
adt-run [06:30:08]: test aa-check: -----------------------]

setting to high, it's essential that packages with autopkgtest pass at least once so they block the promotion next time they fail.
