perf tools: Handle PERF_RECORD_KSYMBOL

This patch handles PERF_RECORD_KSYMBOL in perf record/report.
Specifically, map and symbol are created for ksymbol register, and
removed for ksymbol unregister.

This patch also sets perf_event_attr.ksymbol properly. The flag is ON by
default.

Committer notes:

Use proper inttypes.h for u64, fixing the build in some environments
like in the android NDK r15c targetting ARM 32-bit.

I.e. fixing this build error:

  util/event.c: In function 'perf_event__fprintf_ksymbol':
  util/event.c:1489:10: error: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'u64' [-Werror=format=]
            event->ksymbol_event.flags, event->ksymbol_event.name);
            ^
  cc1: all warnings being treated as errors
