[PATCH 14/15] perf tools: 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.
