Kernel commit 9eea8fafe33e ("libbpf: fix __arg_ctx type enforcement for
perf_event programs") added with 6.9-rc1 tools/include/uapi/asm/bpf_perf_event.h
which for arc, arm64, loongarch, riscv and s390 includes headers from
the arch/${ARCH}/... directories.

Which results in:

  ERROR: perf-1.0-r0 do_compile: oe_runmake failed
  | In file included from 1.0/perf-1.0/tools/include/uapi/linux/bpf_perf_event.h:11,
  |                  from libbpf.c:36:
  | perf/1.0/perf-1.0/tools/include/uapi/asm/bpf_perf_event.h:2:10: fatal error: ../../arch/arm64/include/uapi/asm/bpf_perf_event.h: No such file or directory
  |     2 | #include "../../arch/arm64/include/uapi/asm/bpf_perf_event.h"
  |       |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We copy the uapi/asm directory to make sure the header file is
present.

This is a tweak of the commit from max to only include the uapi/asm
directory.

A second patch will further refine it.
