perf jitdump: Directly mark the jitdump DSO

The DSO being generated was being accessed through a thread's maps,
this is unnecessary as the dso can just be directly found. This avoids
problems with passing a NULL evsel which may be inspected to determine
properties of a callchain when using the buildid DSO marking code.
