kselftest/arm64: Convert za-fork to use kselftest.h
Now that kselftest.h can be used with nolibc convert the za-fork test to use it. We do still have to open code ksft_print_msg() but that's not the end of the world. Some of the advantage comes from using printf() which we could have been using already. This does change the output when tests are skipped, bringing it in line with the standard kselftest output by removing the test name - we move from ok 0 skipped to ok 1 # SKIP fork_test The old output was not following KTAP format for skips, and the numbering was not standard or consistent with the reported plan.
