[ubsan] Fix print_stacktrace=1:fast_unwind_on_fatal=0 to correctly fallback to fast unwinder
ubsan_GetStackTrace (from 52b751088b11547e0f4ef0589ebbe5e57752c68c) called by
~ScopeReport leaves top/bottom zeroes in the
`!WillUseFastUnwind(request_fast_unwind)` code path.
When BufferedStackTrace::Unwind falls back to UnwindFast,
`if (stack_top < 4096) return;` will return early, leaving just one frame in the stack trace.
Fix this by always initializing top/bottom like 261d6e05d5574bec753ea6b7e9a7f99229927753.
