perf symbols: Split the dsos list into kernel and user parts

Browse Source 
We don't need to look at modules in dsos__findnew because the
kernel events come only with user DSOs. Also we need a way to
list just the module DSOs so that we can create multiple sets of
maps, now that we will support maps for the variables in a
symtab.
