perf_counter: Add PERF_EVENT_READ
Provide a read() like event which can be used to log the
counter value at specific sites such as child->parent
folding on exit.
In order to be useful, we log the counter parent ID, not the
actual counter ID, since userspace can only relate parent
IDs to perf_counter_attr constructs.
