perf pmu: Relax uncore wildcard matching to allow numeric suffix
Diamond Rapids introduces two types of PCIe related uncore PMUs:
"uncore_pcie4_*" and "uncore_pcie6_*".
To ensure that generic PCIe events (e.g., UNC_PCIE_CLOCKTICKS) can match
and collect events from both PMU types, slightly relax the wildcard
matching logic in perf_pmu__match_wildcard().
This change allows a wildcard such as "pcie" to match PMU names that
include a numeric suffix, such as "pcie4_*" and "pcie6_*".
