Subject: [PATCH] fix: freebsd build support (#1659)

- Avoid hard-coding the path for bash - this typically is installed as
  /usr/local/bin/bash

- Allow for the fact that FreeBSD's rlimit uses signed integers

Almost all of the test suite passes with three test failures that I
haven't tried to debug yet.
