[PATCH v2 15/20] s390: perf/events: advertise PMU exclusion capability

[Andrew Murray]

The s390 cpum_cf and cpum_sf PMUs have the capability to exclude
events based on context. Let's advertise that we support the
PERF_PMU_CAP_EXCLUDE capability to ensure that perf doesn't
prevent us from handling events where any exclusion flags are set.
