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.
