f2fs-tools: redefine MAX_SIT_BITMAP_SIZE

During mkfs, segment_count_sit is calculated using ALIGN and
SEG_ALIGN, which are both upward. Then, in some extreme scenarios,
such as 16TB, sit_ver_bitmap_bytesize got from segment_count_sit
will exceed MAX_SIT_BITMAP_SIZE, which is calculated in a downward
method.

Unify the two calculating methods and redefine MAX_SIT_BITMAP_SIZE
to prevent sit_ver_bitmap_bytesize overflowing.
