perf: flag __SANE_USERSPACE_TYPES__ to include int-ll64.h for powerpc64

PPC64 uses long long for u64 in the kernel, but powerpc's asm/types.h
prevents 64-bit userland from seeing this definition, instead defaulting
to u64 == long in userspace.
Perf want LL64, flag __SANE_USERSPACE_TYPES__ to get int-ll64.h.

Fix the below issue:
| tests/attr.c:71:4: error: format '%llu' expects argument of type 'long
long unsigned int', but argument 6 has type '__u64' [-Werror=format=]
| tests/attr.c:80:7: error: format '%llu' expects argument of type 'long
long unsigned int', but argument 4 has type '__u64' [-Werror=format=]
|        attr->type, attr->config, fd) < 0) {
|        ^
