perf machine: Set ksymbol dso as loaded on arrival
There's no special load action for ksymbol data on map__load/dso__load
action, where the kernel is getting loaded. It only gets confused with
kernel kallsyms/vmlinux load for bpf object, which fails and could mess
up with the map.
Disabling any further load of the map for ksymbol related dso/map.
