Subject: [PATCH 6.8 392/715] perf bpf: Clean up the generated/copied vmlinux.h

From: Arnaldo Carvalho de Melo <acme@...nel.org>

[ Upstream commit ffd856537b95dd65facb4e0c78ca1cb92c2048ff ]

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.

Fixes: b7a2d774c9c5a9a3 ("perf build: Add ability to build with a generated vmlinux.h")
