gnu: Use license: prefix in (gnu packages samba).

* gnu/packages/samba.scm: Import (guix licenses) with the "license:" prefix to
  solve the conflict between the 'openssl' variables from (guix licenses) and
  from (gnu packages tls). Adjust all license fields.
  (ppp)[inputs]: Simplify list of inputs.
