[PATCH v6 26/26] perf test uprobe_from_different_cu: Scope probe name to PID

[Ian Rogers <irogers@google.com>]

perf probe names the event after the function and binary, so concurrent
runs, as with 'perf test -r3', all add probe_testfile:foo and all but one
fail with 'event "foo" already exists'. Name the event foo_$$.
