perf tools: Add bpf image check to __map__is_kmodule
When validating kcore modules the do_validate_kcore_modules function checks on every kernel module dso against modules record. The __map__is_kmodule check is used to get only kernel module dso objects through. Currently the bpf images are slipping through the check and making the validation to fail, so report falls back from kcore usage to kallsyms. Adding __map__is_bpf_image check for bpf image and adding it to __map__is_kmodule check.
