setup: tolerate `which` failures

If this script is sourced in a shell that has something like
`set -e`, then it fails if the column program does not exist
because the `which columm` fails.  Make a few changes to
tolerate this and not fail:
    - Use $(...) rather than `...`.
    - Use `... || true` when appropriate to allow continuance.
