perf, x86: Clean up IA32_PERF_CAPABILITIES usage
Saner PERF_CAPABILITIES support, which also exposes pebs_trap. Use that
latter to make PEBS's use of LBR conditional since a fault-like pebs
should already report the correct IP.
( As of this writing there is no known hardware that implements
!pebs_trap )
