In order to build with nolibc we need to not include the standard C headers, especially not stdio.h where the definitions of stdout, stdin and stderr will actively conflict with nolibc. Add an include guard which suppresses the inclusion of the standard headers when building with nolibc, allowing us to build tests using the nolibc headers. This allows us to avoid open coding of KTAP output for selftests that need to use nolibc in order to test interfaces that are controlled by libc.
