LOG: Revert "[libc++] Fix the locale base API on Linux with musl" (#169884)

The patch has been committed without approval from the libc++ review
group and is implementing the locale base API in a way it wasn't
intended to be implemented. The commit also contains a no-reply github
E-Mail, which is in conflict with the LLVM developer policy.
