tests: get scripts working in sandbox.sh

Make sure we source the local sandbox.{bashrc,conf} and we always make the
helper functions available when testing even if we aren't interactive.  Now
we can run `make check` and test the local version of sandbox even when we
are running under another sandbox env.
