So that we get kallsyms processing closer to vmlinux + modules symtabs processing. One change in behaviour is that since when one specifies --vmlinux -m should be used to ask for modules, so it is now for kallsyms as well. Also continue if one manages to load the vmlinux data but module processing fails, so that at least some analisys can be done with part of the needed symbols.
