    Allow test of the -D and -L options to succeed or fail with a permissions
error.

    We cannot easily predict what will happen, given the configuration of
    the OS, the permissions on files, the availability of extcap devices,
    the version of libpcap/WinPcap/NPcap (present or future), etc., etc.,
    etc..  Allow those tests to succeed (as would be the case if you have
    the necessary permissions) or fail with a non-command-line-syntax error
    (as would be the case if you don't have the necessary permissions), but
    not to fail with a command-line syntax error.
