perf tools: cleanup initialization of attr->size

Browse source 
The perf_event_attr size needs to be initialized in all cases because it
captures the ABI version.

This patch moves the initialization of the field from the
perf_event_open() syscall stub to its proper location in the
event_attr_init().
