runtime/race: rebuild some .syso files to remove getauxval dependency

We can't depend on getauxval because it only exists in glibc >= 2.16.
Tsan has been updated to avoid that dependency
(https://reviews.llvm.org/D84859). This CL rebuilds the affected
.syso files, and adds a test to make sure we don't regress.

Fixes #37485
