1) Simple code and fix the wrong value of stripe_width by _scratch_mkfs_geom().
2) Get hugepage size by _get_hugepagesize() and replace fixed 2M with
   hugepage size because hugepage size/PMD_SIZE is not 2M on some
   arches(e.g. hugepage size/PMD_SIZE is 512M on arm64).
3) For debugging, redirect the output of mkfs to $seqres.full.
