test: correctly detect ASan on s390x

s390x uses BRAS(L) instead of CALL(Q), e.g.:

```
 1009528:	c0 e5 ff ff f8 a0 	brasl	%r14,1008668 <__asan_report_load1@plt>
 10095f0:	c0 e5 ff ff ea ec 	brasl	%r14,1006bc8 <__asan_stack_malloc_4@plt>
 10097f8:	c0 e5 ff ff f8 f8 	brasl	%r14,10089e8 <__asan_report_load8@plt>
```

x86_64 for reference:

```
  4011f3:	e8 48 fe ff ff       	callq  401040 <__asan_report_load1@plt>
  401227:	e8 24 fe ff ff       	callq  401050 <__asan_report_load8@plt>
  401251:	e8 da fd ff ff       	callq  401030 <__asan_init@plt>
```
