Subject: [RFC/PATCH 28/38] perf tools: Move BUILD_ID_SIZE definition to perf.h

The util/event.h includes util/build-id.h only for BUILD_ID_SIZE.
This is a problem when I include util/event.h from util/tool.h which
is also included by util/build-id.h since it now makes a circular
dependency resulting in incomplete type error.
