Building KVM selftests with musl libc fails across multiple files (e.g. memslot_perf_test.c, cpuid_test.c) with 'ulong' undeclared.
Under glibc, <semaphore.h> includes <sys/types.h>, which exposes ulong. Under musl, <semaphore.h> includes only <features.h>, <bits/alltypes.h> and <fcntl.h>, and does not include <sys/types.h>. As a result, ulong is not visible through the current selftests include chain. include/linux/types.h already defines both ulong and ullong in its sysv aliases block. tools/include/linux/types.h mirrors ullong but omits ulong. Add ulong alongside ullong to close the gap.
