LOG: Add missing call to `__sanitizer::InitializePlatformEarly()` in UBSan's standalone init.

Summary:
While working on rdar://problem/62083617 I noticed this call was
missing.

This is a no-op for all platforms except Darwin. For Darwin this
means the `use_xnu_fast_mmap` flag is initialized as it was intended
when using UBSan in standalone mode.
