add-vmcore: add nodemask_t's size and NR_FREE_PAGES's value to vmcoreinfo_data

[2/3] Add nodemask_t's size and NR_FREE_PAGES's value to vmcoreinfo_data.
  The dump filetering command 'makedumpfile'(v1.1.6 or before) had assumed
  the above values, and it was not good from the reliability viewpoint.
  So makedumpfile v1.2.0 came to need these values and I created the patch
  to let the kernel output them.
