[PATCH 1/1] perf bpf: Clean up the generated/copied vmlinux.h

[Arnaldo Carvalho de Melo]

When building perf with BPF skels we either copy the minimalistic
tools/perf/util/bpf_skel/vmlinux/vmlinux.h or use bpftool to generate a
vmlinux from BTF, storing the result in $(SKEL_OUT)/vmlinux.h.

We need to remove that when doing a 'make -C tools/perf clean', fix it.
