Revert "perf record: Intercept all events"

This reverts commit f5a2c3dc.

This patch is required for making "perf lock rec" work.
The commit f5a2c3dc changes write_event() of builtin-record.c
. And changed write_event() sometimes doesn't stop with perf
lock rec.

[ that commit also causes perf record to not be Ctrl-C-able,
  and it's concetually wrong to parse the data at record time
  (unconditionally - even when not needed), as we eventually
  want to be able to do zero-copy recording, at least for
  non-archive recordings.  ]
