Include kvm_test_harness.h first which will include kselftest_harness.h for _GNU_SOURCE to get defined first before inclusion of stdio.h. It is required for declaration of asprintf(). It removes the following build error caught by clang-17:
In file included from x86_64/fix_hypercall_test.c:12: In file included from include/kvm_test_harness.h:11: ../kselftest_harness.h:1169:2: error: call to undeclared function 'asprintf'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 1169 | asprintf(&test_name, "%s%s%s.%s", f->name, | ^
