hotplug/cpu_hotplug: cleanup

Modify Makefile.

Some cleanup of cpuhotplug0*.sh:
  Obtain some variables' value from parameters.
  Use functions in test.sh, eg. tst_brkm.
  Use 'TST_CLEANUP' shell variable.

Fix error in the procedure of offline/online cpu.

Modify 'sar' command in cpuhotplug06.sh.

Currently cpuhotplug01.sh is disabled, because some irqs'
smp_affinity can't be set.
