runtime/race: rebuild darwin syso to work around macOS 12 malloc reserved address

On macOS 12 a new malloc implementation (nano) is used by default,
and apparently it reserves address range
0x600000000000-0x600020000000, which conflicts with the address
range that TSAN uses for Go. Work around the issue by changing the
address range slightly.

The actual change is made on LLVM at https://reviews.llvm.org/D114825 .
This CL includes syso's built with the patch applied.

Fixes #49138.
