From: Max Krummenacher <max.krummenacher@toradex.com>

Starting with kernel 5.19-rc7 perf changed from using distutils
to setuptools.
Add this to the dependencies to be prepared.

I think this needs something like:

diff --git a/meta/recipes-kernel/perf/perf.bb b/meta/recipes-kernel/perf/perf.bb

to work with 5.19 but we also need to keep older versions working :/
