avoid getpass when not used

some systems (like android's bionic) do not provide getpass.  you can
disable ENABLE_CLI_PASSWORD_AUTH & ENABLE_CLI_INTERACT_AUTH to avoid
its use (and rely on pubkey auth), but the link still fails because
the support file calls getpass.  do not define this func if both of
those auth methods are not used.
