perf/x86/intel: Use INTEL_FLAGS_UEVENT_CONSTRAINT for PRECDIST
My earlier commit:
86a04461a99f ("perf/x86: Revamp PEBS event selection")
made nearly all PEBS on Sandy/IvyBridge/Haswell to reject non zero flags.
However this wasn't done for the INST_RETIRED.PREC_DIST event
because no suitable macro existed. Now that we have
INTEL_FLAGS_UEVENT_CONSTRAINT enforce zero flags for
INST_RETIRED.PREC_DIST too.
