[LTP] [PATCH 03/05] Add Script so the kernel is restored back to its original pristine form

[Subrata Modak <subrata@linux.vnet.ibm.com>]

Once the faults has been injected and all the concerned tests have been run
completely, the kernel needs to be restored back to its original pristine
form so that it is stable again. This Script does just exactly that.
