Kuba Brecka ba85da8482 [asan] Remove system_malloc_zone 
This seems to be dead code – `system_malloc_zone` is initialized as null and we never assign to it. This code is apparently currently never executed (in ASan), but is causes trouble for the TSan OS X port. Let's replace the checks with `COMMON_MALLOC_ENTER` (`ENSURE_ASAN_INITED()`).

Kuba Brecka 465cb8a6fa [tsan] Use malloc zone interceptors on OS X, part 1 (refactoring) 
TSan needs to use a custom malloc zone on OS X, which is already implemented in ASan.  This patch is a refactoring patch (NFC) that extracts this from ASan into sanitizer_common, where we can reuse it in TSan.
