Improve and harden list_active
An upcoming commit will introduce support for the BOSUN_DIR environment variable that allows users (and, crucially, the upcoming test suite) to override the default role directory. Since we have previously assumed that we are in full control of STOW_DIR, we now have to be more careful. Revamp list_active such that the sed invocation no longer gets any user input. This should protect against any nefarious contents in BOSUN_DIR. The new approach used by list_active relies on 'realpath', a GNU-only coreutils program, and its '--relative-base' option which prints absolute paths unless they are below a given directory. This allows us to filter symbolic links that do not point to a path within BOSUN_DIR.
