CA-115035: mpath-boot and multipathed host other-config keys missing

Before upgrading to the new kernel, the output of
multipath -k"show maps"
and
echo "show maps" |multipathd -k
were different.

Now they are the same but previous code in mpathcount.py was
relying exclusively on the wrong output in the previous version.

Now it is fixed in both cases
