Commit b2b9d3a3f0 ("perf pmu: Support wildcards on pmu name in dynamic
pmu events") gives the following example for wildcarding a subset of
PMUs:
E.g., in a system with the following dynamic pmus:
mypmu_0
mypmu_1
mypmu_2
mypmu_4
perf stat -e mypmu_[01]/<config>/
Since commit f91fa2ae63 ("perf pmu: Refactor perf_pmu__match()"), only
"*" has been supported, removing the ability to subset PMUs, even though
parse-events.l still supports ? and [] characters.
Fix it by using fnmatch() when any glob character is detected and add a
test which covers that and other scenarios of
perf_pmu__match_ignoring_suffix().
