Rework the routines to convert a 5.x+ statfs structure (with fixed-size

64-bit counters) to a 4.x statfs structure (with long-sized counters).
- For block counters, we scale up the block size sufficiently large so
  that the resulting block counts fit into a the long-sized (long for the
  ABI, so 32-bit in freebsd32) counters.  In 4.x the NFS client's statfs
  VOP did this already.  This can lie about the block size to 4.x binaries,
  but it presents a more accurate picture of the ratios of free and
  available space.
- For non-block counters, fix the freebsd32 stats converter to cap the
  values at INT32_MAX rather than losing the upper 32-bits to match the
  behavior of the 4.x statfs conversion routine in vfs_syscalls.c
