perf record: Enable the enable_on_exec flag if record forks the target
When forking its target, perf record can capture data from
before the target application is started. Perf stat uses the
enable_on_exec flag in the event attributes to keep from
displaying events from before the target program starts, this
patch adds the same functionality to perf record when it is will
fork the target process.
