sagemath: update to sage-9.5.beta6

Also:
 - rename pkg from sage to sagemath
 - now it will build sage in-place at /usr/lib/sage-$version
 - the resulting pkg contains a lot of useless stuff that comes with the
   distribution; we'll have to clean up. E.g. SAGE_ROOT/upstream is
   definitely unnecessary (1.2G); possibly SAGE_ROOT/pkgs or at least
   SAGE_ROOT/pkgs/sagemath-standard/build (2.6G).
