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.
