btrfs-progs: make free space checker work on non-4k sectorsize filesystems
The value of sector for space cache was hardcoded to 4k, and used to
calculate bitmap sizes. In kernel, the BITS_PER_BITMAP is derived from
PAGE_CACHE_SIZE which is not available for userspace, that can also deal
with filesystem of varying sectorsize.
