[libc-commits] [libc] [libc][bazel] Append '/' to TEST_UNDECLARED_OUTPUTS_DIR (PR #207710)

[Pavel Labath via libc-commits]

https://github.com/labath created https://github.com/llvm/llvm-project/pull/207710

The environment variable does not end with a slash, so we need to add one. Without this, the tests work, but don't achieve the intended effect of writing to the undeclared outputs dir.
