Use extra_free_kbytes.sh whenever sys.sysctl.extra_free_kbytes changes



sys.sysctl.extra_free_kbytes property controls the value set to the
/proc/sys/vm/extra_free_kbytes out-of-tree kernel knob. Replace its
use with execution of extra_free_kbytes.sh script which calculates
and sets corresponding value to /proc/sys/vm/watermark_scale_factor
upstream-supported kernel knob.
