Install several optional packages by default.

These are *most* of the packages on which OptionalExtensions in sagelib
are dependent, so those OptionalExtensions are now built as well.

Notable examples that are not included yet are sirocco and meataxe
(don't build on Cygwin yet, but will soon), and fes (lacks a modern
SPKG).
