LU-18244 utils: add 'lfs mkdir -C -N' overstriping support

Adding support of "-N" in "lfs mkdir -C -N" which specify the
overstripe factor for each MDT. While meta-overstriping has already
been introduced (refer LU-12273), this change mainly aligns the
mkdir -C -N with the overstriping behavior OSTs.

- Util side, add range check [-5, -1] if overstriped enabled within
  lfs_setdirstripe().
- Server side, in lod_object.c::lod_ah_init() where the decision of
striping configuration is made, we adjust the ldo_dir_stripe_count
value account for the specified overstripe factor.
- Macro LMV_OVERSTRIPE_COUNT_{MIN, MAX} added indicating the overstipe
  count for each MDT, in -N format.
