Before the change, meta-ibm layer has below:

  bmcweb
  dbus
  dump
  interfaces
  logging
  packagegroups

I do not think it's confusing because it defines the necessary recipes
for ibm machines.

The commit moves everything from meta-witherspoon to meta-ibm, which
makes a machine that inherits meta-ibm inherits everything from
meta-witherspoon.
Is that intended?
Ideally, the recipes (bbappends) in meta-witherspoon has
append_MACHINE so it will not impact other machines. But can we make
sure every single recipe has correct append_MACHINE?
