[kvm-unit-tests PATCH v3 0/5] add shellcheck support

[Nicholas Piggin <npiggin@gmail.com>]

This is based on upstream directly now, not ahead of the powerpc
series.

Since v2:
- Rebased to upstream with some patches merged.
- Just a few comment typos and small issues (e.g., quoting
  `make shellcheck` in docs) that people picked up from the
  last round.

`make shellcheck` passes with no warnings for me after this series.
(You should be able to put patch 1 at the end without conflicts if
you prefer to only introduce the shellcheck Makefile target when the
tree is clean.)

Thanks,
Nick
