On powerpc64 __u64 is an unsigned long unless __SANE_USERSPACE_TYPES__
is defined, so printing and scanning the __u64 fields with %llu warns:
allocinfo_ioctl_test.c:93:73: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 2 has type '__u64' {aka 'long unsigned int'} [-Wformat=]
Define __SANE_USERSPACE_TYPES__, as other selftests do.

KernelCI's powerpc kselftest builds show this. The define makes the same
change on alpha and mips64 and none on the other architectures; the
x86_64 and 32-bit builds don't change.
