perf kmem: Consistently use PRIu64 for printing u64 values

Building the perf tool for 32-bit ARM results in the following build
error due to a combination of an incorrect conversion specifier and
compiling with -Werror:

builtin-kmem.c: In function âprint_page_summaryâ:
builtin-kmem.c:644:9: error: format â%luâ expects argument of type âlong unsigned intâ, but argument 3 has type âu64â [-Werror=format=]
nr_alloc_freed, (total_alloc_freed_bytes) / 1024);
^
builtin-kmem.c:647:9: error: format â%luâ expects argument of type âlong unsigned intâ, but argument 3 has type âu64â [-Werror=format=]
(total_page_alloc_bytes - total_alloc_freed_bytes) / 1024);
^
cc1: all warnings being treated as errors

This patch fixes the problem by consistently using PRIu64 for printing
out u64 values.
