perf tools: Include file offset and event type name in skip messages

Add the perf.data file offset and use perf_event__name() instead of raw
event type integers in the 'problem processing event, skipping it'
messages emitted by process_sample_event() callbacks across annotate,
c2c, diff, kmem, kvm, kwork, lock, report, script, and build-id.

This lets users cross-reference skipped events with 'perf report -D'
output.  Also add explicit #include "util/event.h" and <inttypes.h>
where needed to avoid depending on transitive includes.
