Most of these scripts can probably just be deleted (see issue #2045), but for now it was easier to just mechanically fix the shellcheck warnings in them, rather than think about whether we actually needed the script. Fixes done using shellcheck 0.7.0 with default options. I haven’t tested any of the changes. Signed-off-by: Philip Withnall <withnall@endlessm.com>
