Subject: [PATCH] sal/arm: compiler warning fixed (see
 -Wdelete-non-virtual-dtor)

This commit introduces a virtual dtor in the ArmCPUState class to
prevent the compiler from producing the following warning:
 "deleting object of polymorphic class type 'fail::Gem5ArmCPU' which
  has non-virtual destructor might cause undefined behaviour"
