When a new FS image is created we need to calculate how much space each
file is going to consume.
Fix two bugs in that logic:
1) Count the space needed for indirect blocks for large files.
1) Normally the trailing data of a file is written to a block of frag
size, 4 kB by default.
However for files that use indirect blocks a full block is allocated,
32kB by default. Take that into account.
Adjust size calculations to match what is done in ffs_mkfs routine:
* Depending on the UFS version the superblock is stored at a different
offset. Take that into account.
* Add the cylinder group block size.
* All of the above has to be aligned to the block size.
Finally, Remove "ncg" variable. It's always 1 and it was used to
multiply stuff.
