[PATCH v8 08/19] perf dsos: Skip BPF and OOL DSOs in dsos__find_kernel_dso()

[Ian Rogers]

In machine__process_ksymbol_register(), set the binary type of non-OOL
ksymbol DSOs to DSO_BINARY_TYPE__BPF_IMAGE (which
machine__process_bpf_event_load() upgrades to
DSO_BINARY_TYPE__BPF_PROG_INFO on PERF_BPF_EVENT_PROG_LOAD), and update
dsos__find_kernel_dso_cb() to skip DSO_BINARY_TYPE__BPF_PROG_INFO,
DSO_BINARY_TYPE__BPF_IMAGE, and DSO_BINARY_TYPE__OOL so that
dsos__find_kernel_dso() does not match ksymbol DSOs in machine->dsos.
