Masami Hiramatsu 82de26abdc perf tools: Fix __dsos__addnew to put dso after adding it to the list 
__dsos__addnew should drop the constructor reference to dso after adding
it to the list, because __dsos__add() will get a reference that will be
kept while it is in the list.

This fixes DSO leaks when entries are removed to the list and the refcount
never gets to zero.

Refcnt debugger shows:
