fix some -Wundef warnings
Commit Message
While I was fixing -Werror warnings I noticed a couple that haven't
yet become fatal (since we are waiting on -Wundef to be added) but I
figured I might as well fix them. Any reason not to commit these?
They both seem very straightforward.

* sysdeps/unix/sysv/linux/tst-setgetname.c (do_test): Use #ifndef
instead of #if to avoid a Wundef warning.
* stdlib/tst-limits.c (do_test): Likewise.
