Subject: tests: Collect script output as binary, collect systemd journal, fix
 lxd.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This adds collection a gzip compressed systemd journal on systemd systems.
The file can later be reviewed with:
  zcat system.journal.gz > system.journal
  journalctl --file=system.journal [-o short-monotonic ..]

To support this:
  * modify test harness infrastructure to not assume content is utf-8.
  * fix lxd platform to support make '_execute' return bytes rather
    than a string. https://github.com/lxc/pylxd/issues/268

Also switched the base collectors to use /bin/sh as others already did.
