asan_ignore: Explicitly list ignored behavior fcns
Overflow on signed integers is undefined behavior. Perl does whatever
the underlying compiler does in this case. Previously this file used a
wildcard which could specify more functions than we really expect to see
this potential overflow from. It is safer to mention explicitly all the
functions.
