Thomas Weißschuh e9df4c6107 selftests/nolibc: avoid passing NULL to printf("%s")
[ Upstream commit f1a58f61d88642ae1e6e97e9d72d73bc70a93cb8 ]

Clang on higher optimization levels detects that NULL is passed to
printf("%s") and warns about it.
While printf() from nolibc gracefully handles that NULL,
it is undefined behavior as per POSIX, so the warning is reasonable.
Avoid the warning by transforming NULL into a non-NULL placeholder.
