 Port diagnose PATH check improvements

 Get shell from dscl instead of assuming bash. Don't try to check the
 value of PATH with shells we don't know about. The code to add our dirs
 to PATH only works with bash, so don't offer to do it with other
 shells. Use the interactive questions API instead of reimplementing it.
