equiv: if a variable is only equivalent to itself set ->equiv to NULL
On the one hand, this change make sense.
On the other hand, there was a bug parsing some kernel code where the
equiv list did not contain the variable itself but just contained another
variable two times. How did that happen? add_tracker_list() is supposed
to prevent duplicates.
I suspect that this patch just papers over that bug. :/ So probably we'll
see it again some day.
