export isl_basic_set_sample_point and isl_set_sample_point
export isl_basic_set_sample_point and isl_set_sample_point

In analogy with isl_union_set_sample_point, exported in 34cf899
(add isl_union_set_sample_point, Mon Aug 31 15:00:51 2015 +0200).
These extra exports are not strictly needed because basic sets
and sets are subclasses of union sets.  In the python bindings,
isl_union_set_sample_point would therefore also get called
on basic sets and sets.
