Add __used to __CTOR_LIST__ and __DTOR_LIST__

Browse Source 
Enabling BSD_CRTBEGIN on amd64 resulted in
error: unused variable '__CTOR_LIST__'.

__CTOR_LIST__ is indeed unused in crtbegin.c; it marks the beginning of
the .ctors array and is used in crtend.c.  Annotate __DTOR_LIST__ as
well for consistency.
