perf tools, powerpc: Fix compile warnings in tests/attr.c
We print several '__u64' quantities using '%llu'. On powerpc, we by default include '<asm-generic/int-l64.h> which results in __u64 being an unsigned long. This causes compile warnings which are treated as errors due to '-Werror'. By defining __SANE_USERSPACE_TYPES__ we include <asm-generic/int-ll64.h> and define __u64 as unsigned long long. Changelog[v2]: [Michael Ellerman] Use __SANE_USERSPACE_TYPES__ and avoid PRIu64 format specifier - which as Jiri Olsa pointed out, breaks on x86-64.
