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);
