Avoid to record execontext used for origin tracking when --trac-origins=no
All calls to VG_(unknown_SP_update) were recording an execontext
of one IP, useful only for track origin.
This patch implements splits VG_(unknown_SP_update)
in two different functions VG_(unknown_SP_update_w_ECU)
(doing origin tracking) and VG_(unknown_SP_update) (not doing origin tracking).
