this is a global object allocated by the allocator, so we can suppress this report.

d074e910df qa/lsan.supp: update heap_profiler suppression and ASAN_OPTIONS 
In continuation to: 8c099a5340

Regsiter singleton leak seems to be replaced by:
```
-----------------------------------------------------
Suppressions used:
  count      bytes template
      1          8 ^InitModule
-----------------------------------------------------
```

In similarity to Crimson's suppression: 6ed8d839b4

8c099a5340 asan: add qa/lsan.supp for leak sanitizer suppressions 
any executable that links against the heap_profiler leaks 8 bytes for a
singleton:

the python script bin/ceph has a lot of leaks:
