[RFC V2 1/3] perf, tools: Support wildcards on pmu name in dynamic pmu events

Agustin Vega-Frias [off-list ref] writes:

An option to keep backward compatibility and consistency would be
to wrap the pattern/string passed in *'s, that way we can just use
fnmatch and have all the examples Jiri brought up work the same.
With that in place we can actually also drop the explicit ignoring
of the uncore_ prefix since the globbing would take care of that.

Prepending with * would seem dangerous, could result in false
matches. But adding it at the end should be ok.
