Shellcheck fixes round 3

Now using the version that's
present in the bionic images.

Meaning we have more warnings
but can also set the minimum
level to ignore a lot of them.

Fix the check for whether
shellcheck supports --severity.
(we have pipefail on, but we
expect shellcheck to fail in
this case)
