Add missing call to `Symbolizer::LateInitialize()` in UBSan's standalone init.
Summary:
This fixes symbolization in Standalone UBSan mode for the Darwin simulators.
861b69faee5df8d4e13ef316c7474a10e4069e81 (rdar://problem/58789439) tried to fix
symbolization for all sanitizers on Darwin simulators but unfortunately it only
fixed the problem for TSan.
For UBSan in standalone mode the fix wasn't sufficient because UBSan's
standalone init doesn't call `Symbolizer::LateInitialize()` like ASan
and TSan do. This meant that `AtosSymbolizerProcess::LateInitialize()`
was never being called before
`AtosSymbolizerProcess::StartSymbolizerSubprocess()` which breaks an
invariant we expect to hold.
The missing call to `Symbolizer::LateInitialize()` during UBSan's
standalone init seems like an accidently omission so this patch simply
adds it.
