[libc] Update some syscall tests to be more tolerance to QEMU behaviors. (#208920) Also expand ErrnoSetterMatcher to allow multiple errnos. This will allow us to enable riscv64 qemu precommit CI. To be revisited next year to see whether those are still needed by then: https://github.com/llvm/llvm-project/issues/209273 Assisted-by: Gemini 3.5 Flash
