gnu: ntl: Update to 11.4.3.

* gnu/packages/algebra.scm (ntl): Update to 11.4.3.
  [source], [home-page]: Use https URL.
  [source](snippet): Remove bundled libtool.
  [inputs]: Add gf2x.
  [arguments](configure): Use invoke insteam of system*. Remove the no longer
  supported WIZARD argument. Add a LIBTOOL parameter, since it's now
  required. Enable building with gf2x. Pass the paths to dependencies
  explicitly.
  (eclib)[inputs]: Remove the transitive dependency on gmp, which is now
  handled automatically by libtool.
