Remove antiquated code that can cause problems

Now that hwloc is providing better definition of
"allowed" cpus, we no longer want/need to be
doing an explicit read of the local affinity.
This was incorrectly being applied to all
daemons because we assumed that any externally
applied binding (e.g., cgroup) would apply to
all locations - mpirun as well as compute
nodes. Sometimes isn't true, so just avoid
the complications.
