ec/ecp_nistz256: harmonize is_infinity with ec_GFp_simple_is_at_infinity.

RT#4625

(Imported from upstream's e3057a57caf4274ea1fb074518e4714059dfcabf.)

Add a test in ec_test to cover the ecp_nistz256_points_mul change. Also
revise the low-level infinity tests to cover the changes in
ecp_nistz256_point_add. Upstream's 'infty' logic was also cleaned up to
be simpler and take advantage of the only cases where |p| is infinity.
