cpio tried to find a file at ${S}/tools/perf and failed
if the input list is not valid.
Make a copy of kernel shared source directory into a perf workdir
could fix the issue.
Drop `Fix for rebuilding' which is obsolete

I probably would have used "cp -a -r", or similar. Since it
is possible that a kernel may not actually be a git repo (linux-yocto
always is, but that is just one data point).
Also, did you try just copying the tools SRC dir + whatever
infrastructure is needed to build ? That will save us a LOT
of i/o when moving the source around for perf to build.
But outside of those details/mechanics, the approach is sound.
