perf tools: Add machine__module_dso function
Separate the dso object addition and update when adding new kernel module. Currently we update dso's symtab_type any time we find it in the list, because we can't distinguish between new and found dso from __dsos__findnew function. Adding machine__module_dso that separates finding and adding new dso objects, so there's no superfluous update of dso.
