Description: ziomon: Fix handling of multiple multipath devices
Symptom:     Specifying more than one multipath devices produces a 'device
             does not seem to exist' error. E.g.

               ziomon -i 10 -d 1 -o test /dev/mapper/mpatha /dev/mapper/mpathb
               Check devices...
               ziomon: The following devices do not seem to exist:
                  /dev/mapper/mpatha

Problem:     The internal parsing logic that identifies the devices which
             belong to multipath devices does not work in later versions of
             the bash shell.
Solution:    Switch the internal parsing logic to use a bash-independent
             construct.
